The line comes from Machuca, the 2004 Chilean drama film directed by Andrés Wood and set in Santiago during the political turmoil of 1973. Within Chile the clip was shared for years as a familiar piece of schoolyard slang from the movie, then spread wider through Latin American meme pages, WhatsApp forwards and short video edits. Its appeal is less about the film's serious story and more about how instantly recognisable the delivery is, so it now works as shorthand for urging someone on.

Pégale po weón is a Chilean meme line from the film Machuca, shouted to urge someone to hit back, now used in funny fight and reaction edits.
This is a short, shouted Chilean Spanish line where a voice yells 'pégale po weón,' with the rough, urgent delivery of a kid egging on a fight. The 'po' and 'weón' make it unmistakably Chilean slang, casual and a little aggressive at the same time. It lasts just a few seconds but carries a lot of energy: part taunt, part encouragement, part chaos. When it is dropped over a clip, it instantly turns a scuffle, argument or playful push into a joke, as if an unseen friend is standing nearby demanding action.
