Bomboclat comes from Jamaican Patois slang used as a strong exclamation, and online it has been adopted as a meme shout for surprise and disbelief. The do Duarte version is shared as a short standalone clip on soundboards, where its name helps users find that specific delivery among many similar reaction sounds. Its popularity comes from how portable it is: one shouted phrase can caption a fail, a reveal, a roast or a chaotic cut without needing any extra context or explanation.
