Stoopid comes from Tekashi 6ix9ine's 2018 single STOOPID, featuring Bobby Shmurda, from his debut album Dummy Boy. The shouted hook was clipped by fans and spread across YouTube, TikTok and soundboards as a standalone reaction, in the same family as bruh and emotional damage clips. Its brevity helped it travel, since a single insulting word needs no setup and can be dropped into gaming, sports or everyday fail videos. It remains popular because the delivery sounds both angry and cartoonish at once.
