The Text That Started My Internet Slang Obsession

Last year my nephew texted me “that’s bussin fr fr no cap” after I sent him a picture of a burger I made, and I genuinely had no idea if he was complimenting me or roasting me.

I typed back “thanks?” with a question mark because I was that unsure.

That moment kicked off something I didn’t expect — a weirdly deep dive into internet and Gen Z slang that lasted way longer than it should have.

I started noticing these words everywhere: in comment sections, in my coworker’s Slack messages, even in ads. So I decided to actually pay attention, use the words myself, and see what happened.

Spoiler: I got some things very wrong before I got them right.

Why Slang Feels Like a Moving Target

Here’s the thing nobody tells you — slang doesn’t work like a dictionary. It’s not static. A word can be “cool” on Monday and completely cringe by Friday if the wrong person starts using it.

I learned this the hard way when I used “yeet” in a work email (don’t ask why, I don’t fully know either) and a younger coworker gently informed me that word had “expired” like two years ago. Apparently slang has an unofficial shelf life, and using outdated slang is almost worse than using none at all.

That’s really the first lesson: slang isn’t about memorizing words. It’s about reading the room, the platform, and the timing.

Where Slang Actually Comes From (It’s Not Random)

Most of the slang blowing up right now traces back to a handful of sources:

• TikTok — probably the biggest engine right now. A sound, a meme format, or a phrase from a viral video gets repeated so many times it becomes shorthand.
• Twitch and gaming communities — words like “gg,” “poggers,” or “clutch” started here and spread outward.
• Black and queer internet culture — a huge chunk of mainstream slang (think “slay,” “shade,” “tea,” “read”) has roots in African American Vernacular English (AAVE) and ballroom/drag culture, often picked up and popularized later by wider audiences.
• Twitter/X — quick, punchy phrases that get turned into memes and reused endlessly.

Once I started tracing words back to where they came from, using them felt less like guessing and more like actually understanding the joke.

The Slang I Actually Tested (With Real Reactions)

I want to be honest about what worked and what flopped, because that’s the part most articles skip.

“No cap” — means “I’m not lying” or “for real.” I used this with my sister and it landed fine. Low risk, widely understood even by people outside Gen Z circles at this point.

“Rizz” — short for charisma, usually about someone’s ability to flirt or charm people. I tried this one on my brother-in-law and he just stared at me. Context matters a lot here — it works better among people already fluent in this kind of slang.

“It’s giving…” — used to describe a vibe (e.g., “it’s giving main character energy”). This one is surprisingly flexible and honestly kind of fun once you get the hang of it.

“Bet” — means “okay” or “deal.” Simple, low-risk, works in texts. I use this one the most now, mostly because it saves me from typing “okay” fifty times a day.

“Delulu” — short for delusional, usually self-deprecating (“I’m delulu for thinking he’ll text back”). This one is oddly wholesome once you understand people use it to laugh at themselves, not others.

“Skibidi” and “Ohio” — these came from very specific meme formats and honestly, if you weren’t already in that meme ecosystem, using these just makes you sound like you’re trying too hard. I tried “that’s so Ohio” once and got laughed at, not with.

Step-by-Step: How to Actually Learn Slang Without Embarrassing Yourself

Watch before you speak. Spend a week just observing. Scroll TikTok comments, read Reddit threads, watch how people actually use a word in context before trying it yourself. Context tells you more than any definition.

Check Urban Dictionary, but don’t trust it blindly. It’s useful for a quick definition, but entries can be outdated, joke submissions, or regionally specific. Cross-check with how the word is actually being used in current posts.

Notice who’s using it. If a word is being used ironically or as a joke about older generations catching on late (a whole genre of meme itself), that’s your sign it’s already past its peak.

Start small. Use one word at a time in low-stakes conversations — texts with friends, not work emails, not with people who’ll judge you for trying.

Pay attention to tone, not just meaning. A lot of slang is sarcastic or exaggerated. “I’m literally dying” doesn’t mean actual death. “This slaps” means it’s good, not violent. Tone is half the meaning.

Common Mistakes People Make (I Made Most of These)

Using slang in the wrong setting. Work emails, job interviews, formal messages — just don’t. I learned this after that “yeet” incident.

Mixing eras of slang. Combining outdated words with current ones makes it obvious you’re not actually part of the culture, you’re just performing it.

Overusing it. One or two slang words in a sentence feels natural. Five makes it feel like you’re writing a parody.

Assuming slang means the same thing everywhere. What’s common on TikTok might be totally unfamiliar in gaming Discord servers, and vice versa.

Not knowing the origin. A lot of slang comes from specific communities, and using it without any awareness of that can come across as careless, even if you don’t mean any harm by it.

Some Real-Life Use Cases Where This Actually Helped Me

Once I got more comfortable, slang genuinely helped me connect better with people — not by pretending to be someone I’m not, but by understanding what was actually being said around me.

I could finally follow my nephew’s texts without asking him to “translate.” I understood why a coworker’s Slack message that just said “this is giving Monday energy” was funny.

It’s a small thing, but understanding the language people around you are using makes conversations feel less like a generational gap and more like an actual connection.
