A viral slang trend centered on the phrase "67" is disrupting classrooms across Texas and the U.S., as students repeatedly shout it in response to the numbers six and seven, regardless of context. Popularized by social media, a rap song, and a 6'7" basketball player, the phrase has frustrated teachers who are banning it or using creative discipline. The phenomenon reflects how quickly teen slang spreads online, with experts viewing it as a temporary trend destined to fade, much like past youth phrases.
