Describing a person (Usually age 30+) who lives in their parents basement, and would rather play video games such as WoW/Counter-Strike or hang out in online chatrooms/IRC than go out into the real world and have a tangible social life.

In most cases, a poopsock is also a basement virgin.
I have not seen Jeff since World of Warcraft was released, He must have turned into a Basement Virgin.

Jeff! Get off your computer and stop being such a Basement Virgin, or I will stop cooking with cheese.
