Rating something with thumbs up or down comes from simple review shorthand, and exaggerating it to four thumbs down turns a normal negative review into absurdist comedy. Online, the clip circulates on soundboards as a quick reaction for fails, flops and bad opinions, where users need a verdict that needs no explanation. Its appeal is the escalation: one thumb is criticism, two is a pan, four is so over the top that it loops back around to funny, which keeps it useful for edits, streams and group chats.
