Ass Crack Fever 

Catching a nasty STD from anal sex. Usually from a filthy whore or or prostitute.

What is it doc? I feel horrible and I think my cock is going to rot off.

Have you had anal?
Yes.

Was he or she clean?
No. She was a street walker and gave it up for $5 so I had to clap them cheeks. Wouldn’t you?
Ummmm. No. That’s nasty. You have the ass crack fever. Here is a script now go soak your penis in bleach.

ass crack butterfly 

When you stick you dick parallel to the cornhole of a girl and slide up and down her ass crack, thus, making your dick look like the thorax and the cheeks looking like the wings.

Zach said he wouldn't mind give Raggity an ass crack butterfly, I wouldn't mind, either.
