stip beer bong
 

I don't know the rules, but it looks like a fun game.
Sorry i have only 3 pics

It's called funnelling
 

I used to do this at alot of parties I went to. Rules always varied. This looks like strip funnelling, if you can't take it all down you loose a piece of clothing. Wow when I think of how much beer I drank like that it amazes me. My motto used to be beer is food, and i truly lived by that back then. Had to stop doing that and although I haven't drank in 13 years I probably got enough in me for the next 13 years.
