The line comes from Portal 2, Valve's 2011 puzzle sequel, where Wheatley is the talkative personality core who tries to take over Aperture Science and repeatedly taunts the player. Clips of his voice lines spread through gaming soundboards and short-form edits, where the absurd schoolyard insult stood out because it was so out of place coming from a robot. It remains popular because it is instantly recognisable to Portal fans, short enough to drop into a single beat, and funny without needing any context from the game.
