I dont know what this word means.

Weeabo is intended to be a derogatory insult, along with Wapanese. Incidentally, "Otaku" is considered an insult in Japan. They think it's weird that foreign Фаны are proud to call themselves as such.

A nicer way to think of it is that anyone who calls Ты a Weeabo is xenophobic as hell & resents Ты for not thinking their preferred culture is superior in every way.

It's primarily aimed at shameless obsessive otaku, especially the noobs who have only been into Аниме for about 5 years. But much like how Hipster has Остаться в живых all meaning & has no definitive definition, it's also used by Аниме haters to describe anyone who likes anime.

Also used within the fandom, aimed at passionate noobs, used by older Фаны who've long settled into the fandom like a marriage where Ты stay because it's familiar, but the romance is gone. The noobs remind them of how embarrassing they themselves once were.

Anyway, Weeabo characteristics are the following:
*Bringing Аниме & Манга into any conversation it has no business being.
*Wearing cosplay outside of a convention.
*Proudly displaying your poorly drawn shipping fanart on the internet.
*Being able to name all the Pokemons AND not hating the Final Фэнтези franchise.
*Constantly reminding people that English Музыка sucks & American musicians are unattractive (still guilty as shit of this on my part).
*Being a proud & open Фан of yuri, yaoi, shotacon, lolicon, sibling complex, или furries. (Guilty of some of this too, but America needs to get over it's damn homophobia already).
*Using Japanese words in conversations with non Аниме fans. (Incidently, this also irritates the shit out of seasoned Аниме veterans).
*Getting extremely defensive when another otaku points out that your're mispronouncing a word или using it incorrectly.
*Having a ship-to-ship combat in public.
Getting toxic when еще well-behaved otaku tell Ты that your embarrassing yourself as well as them.
*Owning an obscene amount of UFO cather Куклы & NECA figurines.
*Owning a мышь pad with a boob armrest & a body подушка with a naked Аниме character on it.
*Having hentai, wallscrolls, & Манга posters on your walls instead of pinups of real people.
*If being a Фан of Аниме is literally your only defining characteristic at school, then Weeabo is actually a well-deserved Название used to label a one-character.

From what I've heard, a weeaboo is a person that says they know everything about anime/is an Аниме fan, but actually doesn't. Ты probably aren't a weeaboo, though. If Ты don't want to seem like one, refrain from over using words like "kawaii" "desu", etc.

Basically it means someone who likes Аниме A LOT to the point where they put Япония on a high pedestal and think it's the best place on earth and it's only Аниме and they generally put down America/other countries to make Япония look better and they force Аниме onto other people and can't understand why a person doesn't Любовь it. It's really not a nice thing to call someone, and there's a lot of negative traits associated with it including forcing (usually yaoi) parings on people, harassing Asians (because they think they're all Japanese) really bad cosplay in inappropriate places, speaking in broken Japanese pretending to know the language (desu, sugoi, kawaii,and neko are usually some favorites), and drawing bad fanart/fanfictions and forcing people to look at it thinking they're the best and that they have no need for improvement, the Список goes on, if Ты want here's a funny tumblr all about people's encounters with them.

When you're friend сказал(-а) you're a weeaboo for Len they probably meant that you're super obsessed, think he's the best singer ever etc. Now I don't know Ты или them или how they сказал(-а) it so they may have just been joking, but Weeaboo is usually meant as an insult.
