Teachers are exhausted — and this time, it’s not because of homework or grades. It’s because of “six-seven.”

A new viral classroom trend has spread like wildfire across schools, and educators say it’s driving them up the wall. Every time a teacher mentions the number six, kids burst out laughing — then shout “six-seven!” in unison. “I’m gonna start kicking people out,” one frustrated teacher joked after hearing it for the 100,000th time.

The phrase comes from a rap lyric in Skrilla’s “Doot Doot,” where the words “six-seven” are repeated for no reason. But for kids, it’s catchy enough to turn every math question or sentence with “six” into a comedy routine. “I was just asking about a graph,” sighed teacher Kaitlyn Biernacki, “and chaos broke out.”

Teachers say it’s another sign of how social media is reshaping classrooms — and attention spans. As one put it: “These kids don’t know how to stop.”

Maybe it’s time the next trend teaches patience — not disruption.
