IN the MMORPG World of Warcraft, specifically on the Undermine realm, the Term "Piece of Bitch" or "POB" for short, is used to define any player who succeeds in mundane achievements, fails excessively, or for the most part, does not know how to play their class or the game.
DO NOT BE FOOLED! - THIS IS MOST DEFINATELY NOT AN INSULT!!
Someone who is a skanky piece of bitch is someone who is exactly the opposite of the words used! (skanky and bitch)!
A skanky piece of bitch is someone who you would call your best mate (male or female), who is always there for you and is generally a bit of a legend!!
