Very similar to trench foot caught by soldiers during
world war I, trench cock is obtained after a long night of rough fucking in which both parties fall asleep while the male's one eyed
battering ram remains inside the female's pork wallet. The
excessive amount of moisture exposed to penis causes it to saturate and smolder causing the infamous trench cock. Extreme cases have resulted in the male genitalia sloughing (falling) off.
Friend #1: Hey bud how did last night go with that slut you scooped up from the
titty club?
Friend #2: Aw man it was going great, I was really pounding
that shit when we both
passed out.
Friend #1: What is the big deal about that?
Friend #2: Well I fell asleep with my cock still inside her.
Friend #1: And?
Friend #2: Well I am worried I may have gotten trench cock and now my junk might fall off.
