Rumpled Crotch Syndrome 

The social faux pas (similar to vpl on a lady) for a gentleman or Sloane Ranger to wear trousers which are two large resulting in creases and suspicious-looking cloth bulges in the groin area.

Sadly, however, the trousers which the Prime Minister wore to the Royal Wedding were too big; he was suffering from RCS, rumpled crotch syndrome, which afflicted the previous Tory prime minister.

Thermal Crotch Transition

That moment after you jump in the pool but before your genitals get adjusted to the cold water. Also for sitting down in a very hot tub.

1 - As Jimmy jumped in the pool, a thermal crotch transition occurred, and he yelled, "Ahhh my krundle!"

2 - As Jimmy sat down quickly in the hot tub, a thermal crotch transition occurred, and he yelled, "Ahh my krundle!"

Carnivorous Crotch Crickets 

Another way of saying pubic lice, or "crabs".

However the phrase is typically used to describe a promiscuous person that is highly likely to contract a Sexually Transmitted Disease.

Dude, Mary's been with so many guys she probably has carnivorous crotch crickets!

Zip Crotch 

The uncontrollable fear of one day zipping your ballz or penis within the motion of zipping up your pants.

Person #1: Dude, Johnny looks pretty sad over there in the corner. We're at a bar talking to chicks and he's acting like a little bitch.

Person #2: He got the Zip Crotch.

Person #1: ewww nevermind. I understand.

Cheese Crotch 

A crotch cheesier than an order of nachos from 7/11 and smells equivalent to a baseball stadium filled with parmesan.

"Yo did you get laid last night?"
"No bro, she had a cheese crotch."
"Ew. The worst."
"Yeah it was nasty, like extra cheddar."

When ones groin area sweats to the point of smelling cheesy.

After my 3 mile jog, the waft of my walk shared my Gouda crotch with all.
