Hi guys, My name is Yakami-Chan and I am here to educate you guys on what an Otaku is. First off an Otaku is a term used commonly in Japan and in the United States to describe someone who has a Anime/Manga fandom. A Weeaboo is someone who takes it a step to far and disrespects their own culture and attempts to take on Japanese culture as their own.
In modern Japanese slang, the term otaku is most often equivalent to “geek”. However, it can relate to a fan of any particular theme, topic, hobby or any form of entertainment.
In english the term is a loanword from the Japanese language. In English, it is usually used to refer to an obsessive fan of anime/manga and/or Japanese culture generally, and to a lesser extent Japanese video games. All in all an Otaku can be more or less a compliment or an insult, It is the way you use it
A ‘Weeaboo’ is a stereotypically American, who obsesses over the Japanese culture. This is usually thanks to the recent trend of dubbing/translating anime/manga and bringing it to the new culture.
Typically, a Weeaboo will abuse the word “kawaii” to ridiculous levels, and other Japanese words will be completely mangled. Another trend is to obsess over every possible nook and cranny of a given manga, usually one translated by Monthly Shonen Jump, yet will, again, use “oro?” when told of another series, with this new series having much more redeeming values in the way of art, writing, characters, etc. Try it- ask any Naruto-fan what Neon Genesis Evangelion is. Weeaboo is more of an insult then Otaku is.
