Just like the title says.
Weeaboo: 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. Synonym of wapanese.
LOL! He wouldn’t fit in at all, he will have to go back to being Japanese, then he’ll become a GOD.
I wouldn’t be surprised if there is actually Japanese people obsessed with American culture, not as in cartoons but maybe shows and Hollywood and New York’s rich lifestyle.
