History[]
Atatata originates from Fist of the North Star. Where Kenshiro, the main protagonist, goes berserk and starts roll punching extremely fast while screaming ATATATATATATATA for about a minute. The meme is disjointed as there are a thousand and one ways of spelling atatatatatata.
It is even more powerful than "MUDA MUDA MUDA MUDA MUDA MUDA MUDA MUDA" and "ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA" combined.
