The worst name imaginable for a cat...

Blowjob.
"What's your cat's name?"
"blowjob."
"uh... what? with those sharp teeth and that raspy tongue?"
"that's right, and don't you ever forget it! now can I borrow some cat food for blowjob or are you gonna make me go to the store for that?"
"for what?"
"for blowjob."
"you monster."

 

My cat thinks her first name is dammit.

 

It's better than giving that name to a dog. "Blowjob! Come here Blowjob!"

 

Sounds like me on a typical Friday night.
