The Rash 

A deadly pathogen which originates in Korkin City, and comes from bed rotting 24/7, always strikes just before you were about to lock in, there is no cure, and it might be fake.

"I heard of some guy who got the rash? What happened to him?"
"Oh that guy? He never gets on anymore, rots in bed 24/7, and always complains about it now."
"Is the rash even real?"

The Ass Rash Special

Get 3 beers and get two willing female participants. Let them get "drunk". Tell all of you friends that you can't drink because of Islam, and tell the girls that you are "plastered and you want to experiment". Take the already drunk girls and bring them to your room. Proceed to fornicate.

"So did you here about Ali Baba last night? He met these two sluts and pulled The Ass Rash Special!"
