First time prisoner defense

The first time prisoner defense is a self-defense move which involves pooping yourself or your pants in order to avoid being raped.

This can be done by both men and women in any context, but was popularized as a grimy prison tactic.

"Damn, I heard George is going to prison for murder. I hope he brings lube hahaha"

"Hahaha I hope he tries the first time prisoner defense out."
