Porn Induced Erectile Dysfunction. Mainly affecting virgins, when they finally get a chance to have sex, they can't get it up due to having watched too much porn and can only get hard when they watch porn
I took a girl home last night finally but my patheticexistence of watching porn has left me with PIED
Pied is often used to describe a situation in which someone has been "owned" and have been heavily dissed. Pied is often used against blondes as they are usually the most pieable.
