A fork of Rural Dictionary
A very consistent name for the movie.
See, there is an idiom "lock stock and barrel" which means "entirely, from top to bottom".
Also "Lock" is a slang for weed, "Stock" for money, and "barrel" for itself. The major elements in the movie are "copious amounts of ganja", £500,000.00 debt, and two antique shotguns which are used to fight Rory Breaker - who, by the way, is the most cruel and coolest gangster in the world.
It seemed meaningless and lame as a movie name at first, but it all appeared to me when I saw it. It was truely "Lock, Stock, and Two Smoking Barrels".
