bum funnel 

The art of the funnelee laying on the ground, whilst 2 of his friends stand over his face with their bare behinds pressed firmly together thus forming a funnel. A drink of your choice is then poured down the funnel into the waiting mouth of the funnelee.

whilst absolutely leathered and trying to be funny, "lets do a bum funnel!"

bumfunnery 

Anal sex. So called because it involves bums, and is fun.

We got up to some bumfunnery last night.
