The Otaku Dictionary

[Jyunishinsho]

C'mon people, post in all the lingo and words with definitions that an otaku may use.

For starters:

Otaku: The very epitome of a compulsive addict. They like anime  :D !

Follow it up.

Woot!=used as an expression for Happiness, joy or after getting laid XD

KIIYYAA (Kiya): An expression of extreme glee when your fave anime character pops up on the screen, looking cute, funny...or looking damn hot.

Heh, heh I use this one a lot  :D

[Jyunishinsho]

Glomp: Very strong (and sometimes potentially dangerous to the glomped person's health) hug or showing of affection. (See Glomping thread for details)

[Tsubasa]

Woot!=used as an expression for Happiness, joy or after getting laid XD

I think that's just internet lingo.

I'd be more inclined to use "squee," but that's me.

Personally, I'd define it as "obsessive fan."  And it can be fandom of anything really.  There are game otaku, military otaku, etc.
