A non japanese person who basically denounces their own culture and calls themselves japanese. They try to learn japanese through the anime they watch and usually end up pronouncing it wrong and looking like a complete idiot.

KEEP IN MIND: that a non-japanese person can like the culture, watch anime, speak the language and RESPECT THE CULTURE, while still keeping in touch with there own. Which keeps them from being a Weeaboo, japanophile, ect.
Weeaboo's basically disrespect the culture and make complete asses of themselves

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.

A word filter for the image board that replaces the word wapanese. Originates arbitrarily from a Perry Bible Fellowship comic strip wherein a man was paddled by a crowd chanting "Weeaboo! Weeaboo!"
"Those Wapanese kids think Japan is so great."

A non-Japanese person that either considers themselves Japanese, or wishes they were. Often confused with the word otaku which in Japanese is usually referring to a geek, while in English it usually means someone is obsessed with anime, unlike a weeaboo, who is not only obsessed with anime, but the whole entire culture. They are known to use Japanese words in the middle of English sentences, and they are hated by society.
Weeaboo: Konnichiwa Sarah-chan! How did you do on that test, desu?

Sarah: Don't be such a weeaboo.

A weeaboo is a non-Japanese person who is obsessed with Japanese culture. They frequently denounce their own culture, and speak frequently about Japanese culture being superior to others in various ways. Although a weeaboo does not HAVE to be an anime fan, they almost always are. Keep in mind that one can watch anime, and really enjoy it, speak Japanese, and like Japanese culture WITHOUT being a weeaboo, as long as they do not WORSHIP Japanese culture, and abandon or denounce their own.

Weeaboo symptoms include: Having a katana collection, owning an anime body pillow/waifu, denouncing your own culture, and wearing traditional Japanese clothing.
"Holy shit! Did you see the new episode of Naruto yesterday? It's becoming so Americanized now, and all the casuals are watching it!"

1. Any self-proclaiming anime fan who alienates themselve from their own society and assimilate into the Japanese culture from which they know little-to-none about; using their so-called anime knowledge as a guide, which destined them to ultimate failure in assimilation. 2. A special breed of anime fans who put Japan on a pedastol and prefer them over any other countries in terms of multimedia, courtship, etc... (E.g. prefer Japanese/Asian sprouses, prefer J-music > Amer. music, wanna live and die Japan, etc...) As far as anime goes, they know only little. For example, the average weeaboo knows only americanized anime; preferly uncut with jap. audio and eng. subs ( E.g. Naruto, DBZ, Bleach, Haruhi Suziyama, Lucky Star, etc...) and memorized every japanese song from their favorite shows.

Note: Anybody who watches some anime and reads manga are not weeaboos. Those who go over-broaded with their anime, hentai, and pocky obsession are.
A classic example of a weeaboo's presence on the net, this unknown 16-year-old girl's rant about Miyavi:

OMG! I loooove Miyavi!!!
FYI - all you haters - I saved ALL these pictures!!!
Miyavi-desu...aishiteru!!!! hot, so fine, so sexy, so cute, so funny...*dies*

note that Weeaboo love over-using common japanese word/phrases, like kawaii, desu, and aishiteru accompanied by a exclamation mark.

Originally a fictional game from a webcomic name the Perry Bible Fellowship, where one person would say weeaboo and get slapped on the ass with a paddle. This was later adopted as a meme on 4chan when moot got offended by prevailing anti-Wapanese sentiment on /b/. This just gave the /b/tards a new word to insult the wapanese. It is now a derogatory phrase used to insult animu fans who act like faggots on the internets.
A weeaboo can be found on Gaia Online, your schools anime club, or
