Bomboclaat (often spelled Bomboclat) is a Jamaican Patois swear word that transformed into a massive internet phenomenon on Twitter around late 2019. It effectively replaced the 'Sco pa tu manaa' trend, serving as a prompt for users to quote-tweet an image with a funny or relatable caption. While the literal meaning of the word is an expletive related to hygiene products, its digital usage is purely functional, acting as a shorthand for 'Caption this' or 'What is happening here?'. The meme relies on surreal, confusing, or highly expressive photos that provoke an immediate reaction from the audience, making it a staple of viral social media discourse.
