Bomboclat is a Jamaican Patois exclamation used to express shock, anger or disbelief, and it has become a familiar piece of internet slang through Caribbean music, social media and meme culture. Short vocal clips of the word circulate widely as reaction sounds, often paired with surprising or outrageous footage in the same way as a vine boom. Because the word is instantly recognisable even to listeners who do not speak Patois, creators keep using it as a quick, punchy shorthand for a moment that leaves them stunned.
