Every generation develops its own style of humor, and often those jokes leave older groups wondering what they missed. One of the latest examples is the phrase “six-seven” or “6-7,” which has been circulating widely on TikTok and other social platforms. The interesting part is that the phrase doesn’t actually mean anything—and that’s exactly why younger users enjoy it.
The trend took off after hip-hop artist Skrilla released his song Doot Doot in December 2024, featuring the lyric, “6-7, I just bipped right on the highway.” The line quickly became a meme, and within weeks, TikTok users were adding “6-7” to countless videos. People now use it as a playful response to random questions like “What’s going on?” or “Who did that?” simply because it sounds fun and unexpected.
Educators have noticed the trend too. TikTok teacher Mr. Lindsay explained that the phrase is essentially a meme reference, often paired with energetic hand motions. It’s designed to be humorous rather than meaningful. Some teachers, however, say the joke has made its way into the classroom. Elementary teacher Kaitlyn Biernacki shared that students sometimes shout “6-7” during lessons, making it difficult to keep the class focused. Middle and high school teachers report similar experiences, leading some to temporarily discourage the phrase during instruction.
Even with the classroom disruptions, the trend highlights how quickly online humor spreads among younger audiences. If “six-seven” doesn’t make sense to you, that’s completely normal—it isn’t supposed to. The phrase is simply a lighthearted example of how modern memes evolve and how each generation finds new ways to express its shared sense of fun.
