The line comes from Stephen King's IT, where Pennywise the dancing clown uses childlike taunts to frighten and lure his victims, with Ben Hanscom among the Losers he targets. The phrase stuck because it compresses the character's whole threat into a few seconds: a clown's teasing voice carrying a predator's menace. Shared online, it spread through horror fan edits, meme soundboards and short-form videos, where creators reuse it as a shorthand for creepy, unwanted attention. Its brevity and instantly recognisable delivery keep it in circulation long after the film.
