Beerbong

A beer bong is a device for consuming large quantities of beer (or other beverages) rapidly.

The device usually consists of a funnel, connected to a long tube. The tube is filled with beer (with the device being held in a U shape to prevent spillage). The user then places their mouth around one end of the tube, whilst the funnel end is hoisted higher than the 'business end' so that gravity will force the beer down the tube and into the user's mouth at a rapid rate.
