A cry used when your foreskin isn't protecting your bell-end, and something comes incontact with it, such as walking into a table.

Since the nerves from your bell are extra-sensitve, it tends to hurt.
Phil: OH SHIT PETE!!! OPEN-BELL!!!

Pete: What happened man?!

Phil: My foreskin is in pain from walking into that lampost! Oh gawd that hurt...
