A person who is very, very different than a normal fan. A fanboy is someone who has a disturbing obsession with a medium and WILL start verbal world war one if you attempt to point out a glaring flaw of their wonderful, precious,'1337', perfect thing that is SUPERIOR to your preference. Do not try to argue with one, you are only inciting an unwinnable game.
Fanboy: OMG OMG X is 1337!!1!!!111 ur so dumb u dum ugy faggottard fanboy!!11!

Fan of another medium: Actually, X has an extremely cliched plot and dull, invincible protagonists. Really, how many times in the history of movies has-

Fanboy: OMG UR SCH A-

*Fanboy drops several dozen f-bombs on Fan-of-another-medumland. This continues until Fanboy vomits on himself in pure, unadulterated rage.*

From the noun fanboy

v. To stand, drool, or worship the object of their obsession. Fanboying involves no real physical action or movement.

One does not have to be a boy to start fanboying.

He was fanboying in front of that artist. It took the three of us to drag him away from there.

Whenever I fanboy it's like I go into a trance and I block off everything around me.
