Peterbummed
Peterbummed is the correct term used for a male's sexual reproductive organ that is in the state of being bummed or "soft".
The feeling of being "Peterbummed" is usually caused by a friend that either cock blocks, punches you in your "jewls", an erectile disfunction, a man named peter being bummed out, or a situation where you're just not spunky enough when the time to perform arises.
