Hola causas is a piece of Peruvian street slang, with causas used as a warm, informal word for friends or mates, similar to buddies in English. The clip itself circulates online as a short meme greeting, shared in videos, streams and chats where a quick, friendly hello sets the tone. Its appeal comes less from a single famous source than from how instantly recognisable and reusable the phrase is for Spanish-speaking audiences. Because it is brief and upbeat, creators keep returning to it as a casual opener that signals humour, familiarity and a relaxed, informal mood.
