when you have masturbated/released so much that you can no longer move your hand up and down your penis (can not release any seamen either)without screaming out in huge agony. Usually occurs after hentai (scientists haven't been able to explain this supernatural phenomenon).
" No more hentai for me my penis cramp is so bad i just want to cut it off and put it in a hot dog bun"

Just like a calf cramp but in your penis. Drinking more calcium usually helps cure this disfunction.
Bobby: Damn bro, I had a major penis cramp last night.
Daniel: That's crazy dude, got milk?
