Coulrophobia is the term for an extreme or irrational fear of clowns, a phobia that has long been used in horror and comedy because clowns mix bright makeup with unpredictable behaviour. This clip circulated as a Roblox and YouTube shitpost meme, where the joke is shortened to a simple setup and reaction: a clown appears and panic follows. Its popularity comes from that instant readability, letting creators label almost any clown encounter without extra context. It remains in rotation for horror game edits, Halloween posts and reaction videos built around exaggerated fear.
