A game played at a bar by a group of guys which developed from icing. The object is to order your friend a cosmo without his knowledge. Usually other friend distract the victim while the order is being placed. The friend who receives the drink must finish it at the bar but if requested they must walk around the bar showing off their pink drink. The bomb can also be ordered for the friend that was the first to hit the bathroom in the bar. The real joke is that while the drink it very pink it is mostly alcohol. Pinkies out.
Dude I got blackout drunk after three cosmo bombs at the bar last night.
