Austrian Carousel

On an elevated platform, get your buddy naked and in a kowtow position.

Next, you make sure his asshole's nice and lubricated before you open up a beer (preferably chilled) and pour it into his/her ass.

Lastly, you tell him/her to spin around, spraying that anal-beer across the room like a damn fine Austrian Carousel.

Hey Bob, wanna do an Austrian Carousel on that table over there?

Hell yeah, pass me a cold one!

I hope your ass is ready.
