Someones who's life only resolves on anime, manga and video games. They wear products that resolves to an anime or video game and only talk about it. It gets annoying.
"Daww!! What a kawaii sunset!"
"Did you watch the last episode of Bleach?"
"Yeah! It was so sugoii!! Toshiro is so sugoii!!"
"He's not that great..."
"Oh you're a baka!! Kyaaa! Toshiro!! you're so kawaii!!"
*In my mind "weaboo...."

Someone who's world revolves around anime and manga and that's all they freakin' talk about 24/7 because they don't know anything about anything else in the world. They are like otaku's but worse and and major geeks and nerds. AKA Melissa Leonard. They also bash the japanese culture and language by trying to talk japanese and saying KONICHIWA!!! OMG THAT'S KAWAII DESU!!! NYA!
I freakin' hate weaboo's because they are retarded.

An insult used towards people who watch anime, use a few Japanese words in normal sentences (Most of the time learned from anime.), thinks that everyone's opinion is irrelevant compared to their own, and want to move to Japan based on what they've seen from anime. Not to be confused with an otaku, a weaboo is completely different. Sometimes weeb is also said, which is a synonym to weaboo.
Hey, Senpai! Wasn't Biology sugoi today desu?

Pardon?

Oh, you baka!

You're kinda sounding like a weaboo right now...

Usually go by the name of Lawrence or Jasmine, but these humanoid beings, sometimes try to throw you off with an Otis or Josh. They are creatures from a faraway place, called: Japan, they attempt to use trickery of the English language but often slip up with a Japanese word or two. They will often use UWUs in texts, this is a form of assertion of dominance. Beware if you see one, they come in packs up to 4 but on convention days there may be hordes. Save us from pax.
Lawrence: "Ohio Gasimusu"

Literally Anyone Else: "OH NO WEABOO! I'M TOO YOUNG TO DIE!"

Lawrence: "OMAE WA MO SHINDEIRU"

Literally Anyone Else: "WAT?"

Jasmine: "One of us, One of us"

Literally Anyone Else: "Hi I'm Otis now. KUWAI DESU!"

A person who is extremely interested in Japanese culture. Want to be Japanese.
"That guy watching anime over there with the sailor moon cosplay on is such a weaboo!"

A person who thinks they can learn everything about Japan by watching anime. Sometimes denies their own heritage and tries to claim that they're Japanese.
1: guys I know everything about Japan I can speak Japanese because I watch anime
2: weaboo.

Oftenly used as a hate word against anime and manga fans, the definition of this word is very different of how it's commonly and wrongly used.

Weaboo is a non-japanese person so obssessed with japanese culture, manga and anime they think they think everything that comes from Japan is good and superior, some even wanting to become Japanese and hating other cultures for it.

However, weaboos are NOT:

-People who like to watch anime,

-People who like to read manga,

-People who like anime cosplay,

-People who like aspects of japanese culture.

They are people who are EXTREMELY OBSSESSED with it, to the point they think everything that comes from Japan is better and belive they know everything about Japan while they don't.

So, basically, liking anime and japanese culture doesn't make you a weaboo as long as you're not obssessed with it to the point you want to become japanese.
I watch anime and read manga for fun, that doesn't make me a weaboo.

I watch anime and read manga 24/7 , I'm obssessed with japanese culture and I want to become japanese, THAT makes me a weaboo.
