“Anta baka?” is closely associated with Asuka Langley Soryu from Neon Genesis Evangelion, the television anime that debuted in Japan in 1995. The Japanese wording is an informal, confrontational way of asking whether someone is stupid, matching Asuka's combative manner. Short extracts of the line spread through anime edits, reaction videos, soundboards, and messaging clips because the meaning is clear from her delivery even to many viewers who do not speak Japanese. It remains popular as a compact expression of disbelief and irritation.
