The phrase combines common Mexican slang, where buey, also written güey, means dude and no la chingues expresses disbelief at something messed up. Clips with this wording circulate widely as WhatsApp audios and short reaction sounds in Spanish speaking communities online, shared without a single confirmed original recording or scene. Its popularity comes from that everyday familiarity, since the line is something people actually say to friends. Over time it moved from private chats into meme edits, livestreams and soundboards as a reusable reaction for mistakes.
