The testicle that hangs lower than the other one.

basically, poon. spelled backwards.

a boner so hard, so hard you can't even feel it.

when you poop and you can't find it when you're done

originally created as a mixture of the words "noob" and "poop", "noop" means many things. Such as a noob who poops himself, a nerd who poop's himself, or pretty much any jerk who poop's himself. Unlike a noob, a noop can be anyone, no matter their age race or lvl of their guild wars character.

a word like bogus, can be used for anything, also can mean poser.
