Shotgunning

To shotgun a beverage, a small hole is punched in the side of the can, close to the bottom. In order to prevent the liquid from spilling out while the cut is made, the can is held horizontally, tilted slightly, and the hole is made in the resulting air pocket. The hole can be made with any sharp object. Typically, a key, bottle opener, pen, knife, other sharp instrument is used. The drinker then places their mouth over the hole while rotating the can straight up. When the can's tab is pulled, the liquid will quickly drain through the hole into the drinker's mouth.
