The act of doing bosh, usually achieved by swallowing a small quantity of 'bosh'. Larger amounts are highly recommended by tru-boshman, but advised against by the NHS. A group of boshers seeked help for this affliction by phoning the government help line for bosh, Talk to frank.

Frank however was unable to help, and was quickly overwhelmed with boshyness. Some say where frank failed, boshmen succeed.

He's bloody boshing again!

The act of throwing snowballs at cars. The term was coined by Michael DeRobertis of Scarsdale, New York, in the early 1980s. The word comes from the sound made when a snowball is thrown at a car, moving or parked. The term stems from the sound created when a snowball makes a direct hit with one of these "drum-like", hollow panels - "BOSH!!!"
Let's go Boshing - Throwing hard showballs, or iceballs and hitting the "drum-like", quarter panels of cars. "Bosh!!!!"
