what the difference between a otaku and weeboo.

I believe that you are an idiot and should be quiet before you embarrass yourself even more.

you mad or on the rag.
at least jeff was funny

Otaku is an insult as it is mainly used in japan and they are not accepted even in their own culture. Otaku are associated with lazy, obsessive, 2D loving out of shape fat kids that leech off society and probably have some sort or mental disorder. Otaku are the people who have over 9000 figures of the same character and will go bat shit insane if wrongs their favorite character. Although this is what they are associated as. We all know they are very far and in between people like that but it just how they seem to portrayed in Japan.

Weeaboos are just fucking terrible bugs from the earth that must be destroyed. Most weeaboos think Japan is the greatest thing on the planet and that it pretty revolves around anime which as any sane person can tell you it does not. Really good example of that right here. Weeaboos also tend to add Japanese words such as kawaii into their sentences and think that they know what words mean when they really do not. If you have ever been to high school and seen that table of really annoying Japanese obsessed kids then you know exactly what I am talking about. You will see alot of weeaboos in level one Japanese class in college. As you raise through the ranks of Japanese classes you will see less and less weeaboos because by default weeaboos just are not smart. If they were they would not be weeaboos.

America and Japan you got to hide the fact that you like anime. You don't even wanna be a fan. Unless of course its of shows/manga like one piece which I see consistently compared to shows like The Simpsons in the US in terms of "normal or ok to talk about". Stay in the middle ground. Avoid drifting to either side for maximum safety. Don't let anyone know you like k-on.

tl;dr = It doesn't matter what you are just hide your power level at all costs.

Not with those damn scouters

My power level is over nine-fucking thousand; can't hide that shit.

I do agree with your analysis of otakus and weaboos. Having been at a college that offered Japanese as a language of study, it's quite easy to tell who's in it for real and who's in it because it's cool. Like you said, people who only have a lukewarm/weaboo interest in the Japanese language tend to never pass the first level.
