In it's simplest form it is/was called "shotgunning"
I can remember going on the late-lamented Fairstar on a cruise 20 years or so ago with a bunch of mates and doing this (what posessed me). :huh:
The idea is to get a pen, bore a small hole in the bottom of an aluminium can of beer (best when beer is fairly cold), keep your index finger on the hole, place the hole over your mouth, pull the ring on the top of the can... WOOSH!
Final result your cheeks and throat get expanded to buggery and you look a real picture with beer exiting from both nostrils. Better name would be an upper-body beer enema. B)
Most of these highly purile (could be mistaken for recreational) games are gleaned from rather low-brow American College films of the "Porkys" or "Animal House" genre. Generally involving spring break in Florida and women in various stages of undress that may or may not be censored from this forum.
