LADIES, GENTLEMEN, AND THE TRANSGENDERED! I GIVE YOU EVERY SINGLE DEFINITION OF THE WORD "WEEABOO":

1.) A word filter for the image board 4chan.org 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." becomes "Those weeaboo kids think Japan is so great."

2.) 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.

3.) 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.

4.)
1. A person so obsessed with japanese culture that they ignore their own. 2. Someone obsessed beyond healthy levels with anime. 3. People who ruin activities for other people with overzealous references to said anime. 4. People so oblivious to reality they only care about anime. 5. An action worthy of getting one's ass beaten. 1. Inuyasha fans
2. Americans claming to be "Otaku."

5.) 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.

6.) 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.

7.) Someone who thinks Japan is superior over EVERYTHING. Not in reference to someone who likes to watch some anime, reads some manga, eats some teriyaki once or twice a month, etc. The main difference is that a Weeaboo doesn't care about the culture, where a non-weeaboo (I don't know the term, and I don't want to use otaku which is, in fact, a derogatory term) does. A weeaboo speaks Wapanese (i.e. Kawaii neko!! Can I hug your neko-chan?). However they are not to be confused with someone who is still learning Japanese. A weeaboo will obsess over no more that ten anime/manga and then claim to know EVERYTHING there is to know about Japan. They base the majority of their knowledge, if not all of it, of Japan on really bad anime. Not decent ones like Pretear or Suzumiya Haruhi. Shit ones like DBZ.

8.) A game whereby the one who is caught saying the word weeaboo must be chained to a pipe and paddled by all around him/her. Those with the paddles must chant weeaboo until the paddling is finished and the one chained to a pipe is released.

9.) A self-hating Otaku

10.) get this def on a mug A person who's totally obsessed with Japanese culture; Wapanese; Wanna be Japanese.

11.) someone who lives, breathes, sleeps and dreams of anime; a weeabish isn't attracted to real people but rather anime girls/boys
