Someone who is obsessed with Japan/Japanese Culture/Anime, etc. and attempts to act as if they were Japanese, even though they're far from it. They use Japanese words but usually end up pronouncing them wrong and sounding like total assholes. You can find alot of these faggots clogging up the forums of Gaia Online, hanging out in the international aisle of the supermarket, or crowding the manga section of your local bookstore. Synonym of [wapanese].
> I told that weeaboo girl over there that Inuyasha sucks. She slapped me across the face and proceded to cuss me out in Japanese.
