Replying to Butt chugging

Ok nsg, here goes. I made a bet with my friends today. I said that i would butt chug a beer at the next party we all attend for another free beer. I'm totally cool with downing several at once normally through my mouth, no problemo. but i heard that alcohol is absorbed much more efficiently through your asshole. Basically i need advice from the frat bros of ns: do i have anything to worry about chugging a single can of beer through my ass? thank you and jah bless.
