Short version: it’s the “6-7” (pronounced “six seven”) Gen Alpha meme on TikTok—kids say “six seven” with a goofy up-down palm gesture. It’s mostly meaningless on purpose, sometimes used to mean “so-so/maybe,” and that absurdity is the joke. It blew up via TikTok edits, hoops culture (LaMelo Ball at 6'7"), a viral “67 kid” clip, and a rap snippet—then got so big that Dictionary.com literally named “67” its 2025 Word of the Year.
is just use to confuse adult, next time just reply you want 6 or 7 slaps?
