Either way, 2010s slang is a real piece of internet and pop culture history, and understanding it helps make sense of a decade that changed how people communicate online.

This guide breaks down where these words came from, how they were used, and how to tell them apart from older or newer slang.

What Does 2010s Slang Mean?

2010s slang means the informal vocabulary that spread mainly through smartphones and social media between 2010 and 2019. It’s not one word, but an entire language style tied to a specific decade.

This period covered the rise of the smartphone era. Texting shortcuts, hashtags, and short video apps all pushed new words into daily life faster than before.

A word could start on Vine or Twitter in the morning and show up in real life conversations by the weekend.Some 2010s slang described feelings (“salty” for annoyed, “shook” for surprised).

Some described people or things (“basic,” “extra,” “goals”). Others were just fun exclamations (“yeet,” “lit,” “on fleek”). The common thread is that almost all of it started casual, spread through screens, and got adopted by teens and young adults first.

Pronunciation

“2010s slang” is said the same way it reads: TWEN tee TENZ slang. It’s not one single term with a tricky pronunciation  it’s a category name, so each individual word inside it (like “yeet” or “bae”) has its own pronunciation covered in its own entry.

Where Does 2010s Slang Come From?

Most 2010s slang came from a mix of texting shortcuts, hip hop and AAVE (African American Vernacular English), and early social media culture.

The exact origin of any single word often traces back to Black culture and online communities before spreading more widely.

The 2010s were the first decade where smartphones were common and social apps were fast moving. Twitter (launched in 2006 but exploding through the 2010s), Vine, Tumblr, and later Instagram gave slang a way to travel across the country, and the world, in hours instead of months.

A lot of the specific words trace back to African American Vernacular English and hip hop, which have shaped American slang for decades.

Words like “lit,” “fam,” and “on fleek” have roots there before crossing into mainstream teen and internet culture.

For many individual terms, the exact origin is unclear, since slang often spreads informally through group chats and comment sections before anyone tracks where it started.

History of the Term

2010s slang didn’t appear all at once. It built up year by year as new apps and trends took over.Early in the decade, texting abbreviations from the 2000s (like “lol” and “brb”).

Were still common, but new words started mixing in. Around the middle of the decade, Vine and Tumblr pushed short, punchy phrases into daily use. “On fleek,” for example, came from a 2014 Vine video and spread within days.

By the late 2010s, apps like Instagram and the rise of meme culture kept the slang evolving fast. Words like “yeet” and “extra” became everyday vocabulary for teens.

Some of this slang has had a small resurgence. TikTok trends in the 2020s have brought back a few 2010s words as jokes or nostalgic references, even while creating brand new slang of their own.

How People Use It Today

People still use 2010s slang mostly in texting, captions, and casual talk, though often with a joking or nostalgic tone. A few words never stopped being normal to use.

On platforms like Instagram, TikTok, and X (formerly Twitter), 2010s slang shows up in two ways. First, as everyday language that stuck around, like “salty,” “lit,” or “goals.

“Second, as intentional throwbacks, where people use “on fleek” or “bae” ironically to reference the decade itself. In texting and group chats, a lot of this slang still works fine for casual, friendly conversation.

2010s Slang Words

2010s slang words cover a wide range, from feelings to compliments to insults. There isn’t one master list, since new words kept appearing throughout the decade.

Some of the most recognizable words from this era include “lit” (exciting or great), “bae” (a romantic partner), “salty” (annoyed or bitter), “extra” (overly dramatic), “on fleek” (looking perfect).

Early 2010s Slang

Early 2010s slang (roughly 2010 to 2013) leaned heavily on texting shortcuts and the start of Twitter culture. Words from this stretch include “swag,” “YOLO” (you only live once).

But new slang tied to Twitter hashtags and early viral moments started taking over by 2012 and 2013.

Mid 2010s Slang

Mid 2010s slang (around 2014 to 2016) is when Vine and Tumblr really shaped the vocabulary. “On fleek,” “squad,” “bae,” and “turnt” all became widely known during this stretch.

This was also when memes started influencing everyday language more directly. Phrases from viral videos or Vine clips could become common expressions within days, something that hadn’t really happened at that speed before.

Late 2010s Slang

Late 2010s slang (roughly 2017 to 2019) included words like “yeet,” “big mood,” “sksksk,” and “and I oop.” This period leaned into more exaggerated, meme driven expressions, often tied to TikTok’s early days (the app launched globally in 2018).

By this point, slang was moving even faster thanks to short form video. Words could spread across the country in a single viral clip.

2010s Slang vs 2020s Slang

2010s slang and 2020s slang share some overlap, but the newer slang leans more on TikTok trends and Gen Alpha influence. Words like “rizz,” “gyat,” and “no cap” are more tied to the 2020s.

Decade	Common Slang Examples	Main Platform
2010s	lit, bae, on fleek, yeet, extra	Twitter, Vine, Tumblr
2020s	rizz, no cap, gyat, delulu	TikTok

The biggest difference is speed and platform. 2010s slang spread through text based posts and short video clips. 2020s slang spreads almost entirely through TikTok trends and audio clips, making it move even faster.

2010s Teen Slang

2010s teen slang was the vocabulary teenagers used most, often different from how adults or younger kids talked.

Words like “extra,” “shade” (throwing shade means subtly insulting someone), “receipts” (proof of something, usually screenshots), and “salty” were teen favorites.

Teens picked up new slang fastest because they were the biggest users of Vine, Tumblr, and Instagram at the time. A lot of this vocabulary later spread to adults through their kids, students, or coworkers.

2010s Internet Slang

2010s internet slang refers specifically to words that started online before some crossed into spoken conversation.

Terms like “IRL” (in real life), “ship” (wanting two people to be a couple), “OTP” (one true pairing), and “salty” all started in online spaces like forums and Tumblr.

Internet slang from this decade often stayed tied to specific fandoms or communities before going mainstream. Not every internet term made that jump.

2010s Slang Insults

2010s slang insults were usually more playful than harsh, often meant to tease rather than seriously offend. “Basic,” “thirsty” (desperate for attention), “extra,” and “salty” all worked as light insults among friends.

Context mattered a lot with these. Calling a friend “basic” as a joke landed very differently than using it toward a stranger. Most 2010s insult slang worked best in casual, friendly settings where everyone understood the tone.

Outdated 2010s Slang

Outdated 2010s slang includes words that mostly stopped being used seriously once the decade ended.

“On fleek,” “bae,” “turnt,” and “YOLO” are good examples people now mostly use them as jokes or throwbacks rather than genuine slang.

Using these words seriously today can come across as trying too hard or out of touch, since younger audiences now associate them with a specific, older era of internet culture.

2010s British Slang

2010s British slang had some overlap with American slang but also its own flavor, shaped by UK grime music, London youth culture, and British social media users.

Words like “peng” (attractive), “bare” (a lot of something), “safe” (a friendly greeting or thanks), and “innit” (a tag added to sentences) were common in the UK during this decade.

British 2010s slang often stayed more regional than American slang, especially words tied closely to London and grime culture, though some crossed over through music and social media.

Examples in Everyday Conversation

• “This party is actually lit, I’m glad we came.”
• “Don’t be salty just because you lost the game.”
• “She’s my bae, we’ve been together two years.”
• “That outfit is on fleek today.”
• “Yeet! I finally finished my homework.”
• “He’s being so extra about a small mistake.”
• “I’m shook, I didn’t see that coming at all.”
• “Their friendship is relationship goals.”
• “Stop throwing shade, just say what you mean.”

Text Message Examples

• “omg the concert was so lit last night 🔥”
• “bruh why u being so salty rn”
• “just saw bae at the mall lol”
• “my hair is on fleek today ngl”
• “yeet i got the job!!”
• “ur being extra, calm down 😂”
• “im shook rn, did u hear the news”
• “they’re goals fr fr”
• “why u throwing shade for no reason”

Social Media Caption Examples

• Instagram: “Sunday brunch with the squad 🥂 lit vibes only”
• TikTok: “POV: your hair is finally on fleek”
• X (Twitter): “not me being extra about a Tuesday”
• Threads: “salty because it’s Monday, no other reason”
• Facebook: “throwback to when ‘yolo’ was a whole personality”
• Instagram: “goals tbh 😍 #relationshipgoals”
• X (Twitter): “yeet into the weekend like”
• Threads: “bae said we’re staying in tonight and I’m not mad”
• Facebook: “still can’t believe ‘on fleek’ was ever a real phrase lol”

Is It Positive or Negative?

Most 2010s slang is neutral to positive, used for fun, excitement, or playful teasing rather than genuine insults. Words like “lit,” “goals,” and “yeet” are almost always positive or excited in tone.

A few words can turn negative depending on context. “Salty,” “basic,” and “extra” can sting a bit if said with a harsh tone or aimed at a stranger.

But among friends they’re usually lighthearted. Misunderstandings mostly happen when someone outside the intended audience  like a parent or teacher  takes a playful insult too literally.

Who Uses This Slang?

2010s slang was used mainly by teens and young adults during the decade itself, though plenty of adults picked it up too.

Gamers, fans of pop culture, and social media users adopted it quickly because they were most active on the platforms where it spread.

Today, millennials who grew up in the 2010s often use this slang nostalgically or out of habit. Gen Z, who were kids or teens for part of the decade.

Sometimes use it ironically now that newer slang has taken over. Regional pop culture, especially hip hop and UK grime, also shaped who used specific words and how.

Similar Slang Words

Slang	Meaning
Lit	Exciting, fun, or impressive
Fire	Excellent or impressive (similar to lit)
Turnt	Excited or hyped up, often at a party
Savage	Bold, blunt, or brutally honest
Fam	Close friend or friend group

Opposite Words

• Mid  the opposite of “lit” or “fire,” meaning average or unimpressive.
• Basic  sometimes used as the opposite of “unique” or “extra,” meaning plain or predictable.
• Dead (as in “this party is dead”)  the opposite of a lively, “lit” atmosphere.
• Lowkey  the opposite of being “extra,” meaning subtle or understated.

Common Mistakes

People often misuse 2010s slang by applying it in the wrong tone or setting. A common mistake is using “salty” or “basic” as a genuine insult instead of a playful one, which can come across as meaner than intended.

Spelling mixups also happen, like writing “on fleek” as “on fleeq” or confusing “yeet” with “yeat” (a musician’s stage name).

Another mistake is using outdated 2010s slang seriously in 2020s conversations, which can read as trying too hard rather than natural.

When NOT to Use It

2010s slang should be avoided in professional emails, school assignments, job interviews, and formal writing. Words like “lit,” “yeet,” or “salty” don’t fit a workplace tone and can make writing seem unprofessional.

In academic papers, business communication, or any formal setting, plain, standard English is the safer choice.

Using slang in these situations can distract from your message or make it harder for readers unfamiliar with the terms to understand you clearly.
