Bomboclat comes from Jamaican Patois, where it is used as a strong exclamation of shock, anger or disbelief. Online, the word spread first as a caption meme and later as a shouted audio reaction on TikTok, YouTube Shorts and soundboards. This extra large version pushes that trend further, making the voice deeper and louder for comic effect. It now sits alongside other exaggerated reaction clips like the vine boom sound in edits where a single word has to carry the whole joke.
