To masturbate.

The word comes from the phrase "Bash the Bishop" i.e. masturbate. (The Bishop in a game of chess resembles a bell-end.)

When one takes a hodgepodge of alcohols like vodka, whiskey, beer, etc and pours it into a garbage-can sized container, mixes it together and adds fruit punch to make a sweet tasting incredibly drunkening substance known as "Bash". A very popular beverage at old fashioned block parties.
Never drink Bash if you don't want to get hammered.
