Urethra Cactus 

A broad term to describe medical conditions where the patient suffers from being a human. The condition was named in such a way to induce panic in patients when they realize that they are, in fact, human.

Doctor: I'm sorry Sam, but you have urethra cactus

Sam: *pulls out a gun and kills himself*

Urethraholic 

An individual obsessed with pleasuring urethra's, be it there own or others.

That bitch Katie from knife to split was a hardcore urethraholic, never seen a chick cotton swab a dick like she did. As you know, she's dead and in her obituary it reads, "Will always be known as a sweet little girl by the boys down at the homeless shelter, she was abandoned at a young age and you can say Dirty Mike was a bit of a stork when it comes to the taking of children. A lady named Sarah found her after many a soup kitchens had been served in that tight little booty. She quickly discovered Katie had a fetish for putting things in peeholes when she handed her a pen to sign her name, looked away for a second and noticed Katie had placed it firmly in Sarah's urethra. Sarah's pretty much a pimp and collects abandoned hoes from the street, cleans them up a bit and then puts them through the most violent gauntlet fuck fests known to mankind.

narrow urethra 

A curse upon mankind. Only known victim of this curse so far is Hank Hill.

Hank's narrow urethra made him take a minute longer to take a piss, and his chances of impregnating someone is extremely low.
