Is a portmanteau of the words "Wannabe" and "Japanese"

Specifically a White American Anime, or Japanese culture fan, though the definition has been expanded in recent years to include anyone of Western culture(no matter the race) who get hard ons for Japanese culture.

Weeaboos often want to be Japanese and hate Western culture in favor of Japanese, which often most have never even really experience irl, just from Anime. It's more of a phenomenon in gen y due to the fact that they came up in the anime boom, kick started primarily by Toonami, and hyper Japanese gaming of the mid 90s with Playstation.

They are often Anime addicted, and spend tons of money(or their parents money) on anime merchandise, including cosplay, whole DVD boxsets(imported a lot of the times) plushes, and and bad anime video games. They are often pretentious about it(the hardcore ones at least) and think that American animation is crap, not mature, or only uses "crude" art, ignoring the fact that there is nothing mature or realistic about most anime.

Most of the guy weeaboos think they're some kind of romantics, often swooning over anime girls and having no grip on reality because they think anime love is real, and coin themselves as "nice guys" that can't get girls because they're often on the friend line.
Ezra: Hey Steve, do you want to join anime club?

Steve: Nah man, it's full of pretentious weeaboos who look down on you if you like dubbed anime.

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.

Weeaboo: OMGOMGOMG!!!! This is exactly like the yukata Konakona wore in Lucky Star!!! Kawaiiiiiiiiii~!

Ordinary person who appreciates Japan: Hmm, I like this outfit. How much is it?

One, 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 Narutard what Neon Genesis Evangelion is.

This is not to be confused with someone who can tell you who Akechi Mitsuhide is or one who simply appreciates and enjoys popular Japanese (the line is slightly blurred with Otaku, though they're not quite the same). In a nutshell, these are shortsighted, obsessive "noobs," key phrase Over the Top.

Compare and contrast people who do nothing but say "FAIL" all day.

a non-japanese person obsessed with japanese comics/cartoons called anime/manga
here are examples:

1.they commomly only care about anime/manga like for example if a different country invented anime/manga they would be worshiping that country.

2.they use the following japanese words:
(also commonly said wrong and mocking)
-desu (doesnt really have a exactranslation but used as is or mine at end of a sentence)
-kawaii (means cute)
-baka(stupid)

3.in extreme cases a slight insult of anime/manga causes them to overeact and resorts to violence and cussing

unfortunatly this has developed a group of haters called antiweeaboos that sometimes overeact
like if someone reads manga and anime alot yet it isnt there world they would be classified as one

personally being japanese-american I really find weeaboos annoying and i feel offended around them sometimes
yet not all weaboos are horrible people some are just kind,missunderstood,and yes a overboard crazyfans
(this excludes 40 year olds with no life and people that hate everyone that hates anime aka mean weeaboos)
so i feel neutral on the subject.
"U SUX IMA OTAKU NOT A WEEABOO!!"

The ultimate anime fan. (Not to be confused with Otaku or Fangirl/Fanboy)

They have a habit of washing irregularly, are completely obsessed with anything and everything to do with anime and foolishly believe that all Japanese culture is as it is portrayed via an anime.

Often mix (badly pronounced) Japanese into regular English sentences when speaking to produce a 'dialect' of sorts that is not only difficult to understand but also makes them sound like the cheap tourist no one wants to be when on vacation.

Often are fans of yaoi, and think/talk about it non-stop, as they do other anime that have the misfortune of attracting a Weeaboo's attention.
(spelled phonetically)
Weeaboo: Koneecheewa! Have you lost your In you? (Inu = dog)

Normal person: Wha....?

Mostly fat white chicks who go to anime convesions and are obssesed with inuyasha and dye there hair black in poor attempts to be japanese, they often say a few words like konichiwa, baka sayonara and feel as if the know the languge, they also sing anoying theme songs from notable anime shows and show up to school wearing fake cat ears saying there married to inuyasha.
not all weeaboos are fat white chicks they come in difernt shapes and sizes and nationalitys but the majority are big fat nerdy chicks.

A person who is obsessed with anime and says Japanese words, and will scream at someone who says anime is bad, adds Japanese endings to names, and buys useless Japanese weapons. They also have too much of a strong obsession for Japan and only knows things about Japan learned from shows.
Person: Did you see that person who wore Japanese letters on their shirt?
Other Person: Dude, that's a weeaboo, stay away.
