It’s not uncommon to be walking through the school halls and heard someone shout “6-7!” or talk about someone being “mogged” or someone being “so delulu” and wonder, “What is going on?” High school slang in 2025 moves faster than the school bell on half days. Between TikTok, memes, gaming, and so-called “brainrot”, many new words are being used and created all the time.
Why Slang Changes So Fast
Slang changes so fast due to memes and Viral songs, like “Doot Doot (6 7)” by Skrilla, which created the “6-7” trend; the influence of online communities such as Gen Z, Gen Alpha, fandoms, and more; trends spread across TikTok, Instagram reels, Discord, and Snapchat in a matter of hours; and finally, generational identity and humor. Slang is ironic and playful; it’s more about the vibe than the literal meaning, so words can be given creative meanings and multiple uses.
What They’re Actually Saying
Below are some of the top slang terms high schoolers are using in 2025, with how they work in conversation.
Slang is how students express identity, community, and belonging. Some slang reveals what teens are thinking about: performance, comparison, authenticity, and humor. It helps communication if teachers understand slang, bridging generational gaps. A helpful thing for adults to do when dealing with slang is to stay curious. If one ever hears a term they don’t know, they should ask about it in a neutral way. Adults should also remember not to force slang. Although young people may laugh, it shows them that the adult cares about connecting with them. Finally, adults should set boundaries when needed, but also pick moments for connection. Students should remember that slang is powerful. It can include or exclude. Young people should be careful to use slang in ways that build up, not cut down. Being aware of tone is very important as well. Something funny among friends might not translate into class, work, or other professional settings. Finally, it is important to know one’s audience. Not everyone knows what “6-7” or “get sendy” means.
Slang is messy, weird, hilarious, and an important part of the now. Slang isn’t just nonsense. It carries emotion, humor, and identity. Understanding or keeping updated on current slang isn’t about being cool or trying too hard. It’s about listening. Particularly for teachers, understanding one’s students is one of the most important ingredients to making a difference in students’ lives. The words students use and the way they use them show quite a bit about their personality and the way they feel. For people of all ages, don’t be afraid to use the language of the times, but remember: words matter. So the next time someone says, “that was a bop, no cap,” even if one doesn’t understand the words, they can keep these things in mind, nod along, and understand it.
