TikTok creator and educator Mr. Lindsay explained, “It’s just a meme reference. There’s no meaning—it’s fun to say, especially with hand motions.” For many young users, that absurdity is exactly what makes it funny.

Teachers, however, are less amused. Elementary teacher Kaitlyn Biernacki shared that her students started shouting “six” and “6-7” during math lessons, throwing the class into chaos. The phrase has even been banned in some classrooms for being too disruptive.

Middle and high school teachers have reported similar experiences. Counting activities or roll calls sometimes devolve into students chanting “6-7” in unison, making it a challenge to maintain order.

Despite the classroom chaos, the meme highlights how quickly humor spreads online. What starts as a throwaway lyric can morph into a shared cultural joke within days.
