Apologies in advance to my Belgian readers

Him: Would you mind if I added a definition for "blind cavefish" to urbandictionary.com?

Me: What is the definition, exactly?

Him: I dunno yet. Some perverse sexual act that no one actually does maybe.

Me: Funny.

Him: Here's a "blind carl"

Him: 1. blind carl

A blind carl is when you shit on someone's eyes and stick your dick in their mouth.

In order to survive prison, Ethan had to become quite adept at executing a "blind carl" at a moment's notice.

Me: Who does these things?

Me: I mean, I'm not a prude by any means, but seriously. WHO DOES THEM?

Him: Belgians, I suppose.
