Homer Simpson is the central character of The Simpsons, the long-running animated sitcom that began in 1989, and wena po is a colloquial Chilean Spanish greeting, roughly like saying hey or what's up. The meme pairs that familiar cartoon voice with local slang, and the shortened clip has circulated on soundboards, chats and social video as a shareable greeting. Its humour comes from the mismatch between a globally known character and a very local expression, so Spanish-speaking users, especially Chileans, keep reusing it for hellos, reactions and jokes between friends.
