munsterpoo 

What you call someone who spends way too much time on mmorpg sites, such as GaiaOnline, Neopets, and NeoDrama.net. Is usually a pale, pimply 28 year old man who lives in his mother's basement.

Person: Yo, it says you've been online for 20 hours straight! What a munsterpoo!

Person: Hey munsterpoo! How's your online persona going?
