Milhouse Van Houten is Bart Simpson's loyal, bespectacled best friend in The Simpsons, the long-running American animated sitcom known for its Springfield family and schoolyard characters. The casual greeting wazzup, a playful form of what's up, became widespread slang in popular culture around the turn of the millennium. Short voice clips like this one later spread through meme pages and soundboards, where fans reuse recognisable cartoon lines out of context. It remains popular because Milhouse's earnest delivery turns a simple hello into an instantly funny, quotable reaction.
