Someone obsessed with anime to a point where it begins to be insulting.

Someone who speaks in japanese/replaces their name with something "japanese", usually just some word they make up that sounds Asian to them.

See wapanese
Omfg, he's such a weeaboo. He won't get his hand away from dick long enough to realize that his anime isn't real and he's not actually Japanese.

35 year old men who are still virgins living in their mothers' basements. They regularly watch hentei and jack off to Pokémon because they have no fucking life.
When I found out my cousin was a Weeaboo, I went on a treasure hunt to find my favorite rifle.

A non Japanese person who obsesses over anime and tries to learn Japaneses from different series. and in the process disses there own culture and thinks Japan is the only good culture since they invented and perfected anime. KEEP IN MIND that they OBSESS OVER IT. A person who just thinks anime is a cool genre is NOT a weeaboo. A person who has a anime profile picture is NOT a weeaboo, unless they state it themselves. A non Japanese person living in Japan isn't a weeaboo unless it's 100% anime related. If a person who doesn't enjoy anime comes in counter with a weeaboo, remember they are modern humans too and that they will fuck you up if you say the slightest disrespect about anime
Examples of weeaboos:

1.) Body pillows
2.) Very bad Japanese learned from the anime's they claim to have finished
3.) Overreacting about things such as, "I don't approve of Levi from Attack on Titan." Which is a common one
4.) A personal collection of anime related items such as swords used in the anime, clothing items, and etc
Examples of just anime fans.
1.) A decent interest in animes
