Definitions by his ex-wife

pisspuppy 

A retarded, ego-centric individual who craves attention at any level. Commonly applied to someone who always loses arguments, yet feels constrained to continue participation and subsequent destruction. Like their namesake, an abused puppy who knows nothing but maltreatment, than cannot help themselves.

JoeSpareBedroom is the quintessential pisspuppy
