Que onda is a long-standing informal greeting in Mexican and Latin American Spanish, roughly meaning what's up, and amigo simply means friend. The phrase has been used in everyday speech, music and television for decades, which makes this short clip instantly recognisable to Spanish speakers. Online it spread through soundboards, messaging apps and short-form video as a reusable greeting reaction, shared between friends for its upbeat energy rather than tied to one specific show, character or viral moment.
