A weeaboo basically is just an anime viewers that has taken their passion into something more drastic. Basically they start replacing English words such as "Cat" and "Cute" with "Neko" and "Kawaii". They will use these words almost all the time online and offline and abuse them. Also they curse how they aren't Japanese and don't dare to touch stuff such as American video games or watch any American media. "Weeaboo" is an insult because of this. A brief definition is this picture. we are not weebs. dont put us in with that filth
