Peditorosis is the medical term for chronic losing. Peditorosis affects only men and reduces their chances of success with the opposite sex. Symptoms include, but are not limited to: giving a girl too much attention, oozing desperation, being terrified of rejection, and lacking self-confidence. Put simply, you lose your ability to exude awesome or win. Oh and it can be contagious.

Stacy: "Oh I'm so sorry to hear that. That explains A LOT..."
