While in prison, you are unwillingly taking it up the ass, having one shoved in your mouth and giving hand jobs to guys on either side of you.
Hey man, you hear about Lil' Pete getting the Square of Despair in the showers?
When a woman hovers over a sleeping person with their mouth open and slides a bloody tampon out of their vagina into the sleeping person's open mouth, giving you their "Blood Pickle".
"My wife was pissed at me when we went to bed last night. I was awakened by a fresh Blood Pickle in my mouth."
