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.
man that guy's good - he shotgunned the whole thing in under a second!
to call 'dibs' on something you want someone to share with you or give to you.

A sexual act, when a male with a penial piercing is having his dick sucked by a female (no fag shit), and before he ejaculates, he grabs his dick and knocks his penial piercing against her teeth twice to make a "click, click" noise, which imitates cocking a pump shotgun, and then ejaculates in her mouth or on her face.
