The line comes from Hunter x Hunter, where it is spoken to Leorio, one of the series' main hunters, in response to a question the speaker considers remarkably foolish. Clipped from the anime dialogue, it began circulating on soundboards and in short anime edits, where fans recognised both the character and the dry, superior tone. Its appeal has lasted because it works without context: even viewers who do not know the scene understand the put-down instantly, and the Japanese delivery gives reaction videos a sharper, more dramatic flavour than a plain English insult.
