Someone, usually teen girls, who think they understand Japanese culture because they watch a lot of anime. They usually use words like kawaii, desu, itadakimasu, Senpai, and many other Japanese words that these people often dont know the meaning of. They can be seen watching overrated anime like Soul Eater, One Piece, and most overrated of all, Naruto. They are the basic bitches of the anime/manga community.

A derogatory term utilized primarily by Americans to satirize someone who watches excessive anime and/or has a deep fascination with eastern Asia, primarily South Korea or Japan. Weeaboos will often glorify east Asian countries beyond realism, believing it to be a safe haven from everything, despite a large array of problems existing there. A "weeaboo" typically exceeds the average weight of a normal person, and will commonly live in their parent's home at an age exceeding 30.
Keep in mind: An individual possessing these traits can dodge the term weeaboo being applied to them as long as they keep in touch with their own culture, and behave respectfully towards the culture.

Someone who loves anime (Japanese animation) so much that they act like their anime characters, try to speak Japanese, always talk about anime and buy anime merchandise etc. Not all of these make anyone a weeaboo, but doing one of the things that make someone a weeaboo too much can make anyone a weeaboo.
I don't consider myself as a weeaboo, but I sure do love watching anime.
