Piitb, pronounced in the verble form, and I quote "Put it in the bum." Other sources claim it is "butt" not "bum" however these people are wrong and childish, whats sounds cooler Butt (eg "Im homo and that girl has couties on her butt) or bum (eg "She has a nice bum, i'd hit it Brian Pepper style.) Piitb actually came from a small section of the internet known as the misc called the misc, found on bb.com also known as bodybuilding.com .
