This is when the DJ for a themed night (i.e rock/metal/dance etc) plays a few good songs once every 2 hours, the rest is rubbish and appeals only to the fat, ugly and desperate who seem to dominate the dance floor...probably coz no-one wants to go near them.
The act of anal sex when the man urinates into the girl or guys ass, filling the anal cavity with piss. Then remove the penis and smack both ass cheeks together causing the urine to squirt into the air like a water fountain. Then you may drink or not drink.

Guy 2 : "what did you do?"
Guy 1: "I did the old Turkish Waterfountain"
Guy 2: "Thats just sick man"
