The downing of a drink as quickly as possible. The ultimate shotgun requires a bottle of (preferably
non-fizzy)
alcoholic beverage and
two straws.
1. attach the straws together end to end and ensure no side-leaks to air.
2. insert straw into bottle ensuring tip is as near to the bottom as possible.
3. form a food seal around the mout of the bottle and the straw with your lips.
4. tip the bottle up so that it lies vertically (that's straight up and down for all the Americans out there).
5. At the same time open your gullet and have someone else
blow on the other end of the straw as hard as they can.
The contents of the bottle should disappear in under a second - good shit.
6. To ensure it has
gone down and stays down you must now shout "BOOOOOM!" at the
top of your voice. If you spew you have to forfeit.
