When its so hot that your balls sag and slap around till it hurts.

Dude 2: Sounds like a textbook Devil's Swing Set to me.

Devil's Fork

Deviation from steady streamline flow of Urine, in which the piss takes two independent paths, one of which is usually outside the event horizon of the porcelain bowl and often directly incident on trouser leg or shoe.

Includes "Devil's Forking" in which both feet get a hosing and "Devil's Fork Special" a game in which one attempts to secure flow into two urinals simultaneously.

I impressed the lads in the Gents by a spectacular display of Devil's Forking in which I concurrently pissed on the legs of the persons to the left and right of me.

Devil's bargain

An extremely bad deal, with a terrible price to pay, which someone considers accepting because they can see no other way out of a truly horrible situation.
Let's hope their friends can think of some better idea!

He knew she was offering a Devil's bargain, but he would do anything to get the medicine for his wife.
OR
"If you marry that man to put a roof over your children's head, you will be getting the Devil's own bargain, because he does not love them, and he never will."
