bust a cap

To fire a gun (military slang from the days of percussion cap and ball firearms before the manufacture of individual cartidges consisting of a metal casing holding a bullet, gunpowder and a primer that fired when struck by a firing pin or hammer.)

We heard some people busting caps a couple of klicks up the trail.

bust a grumpy

To have to go number 2.
To poop.
To make naughty water.

Brennen had to go bust a grumpy, becuase he'd tried to move and built up enough bodily waste to kill an elephant.

old and busted

Worn out, used up, overplayed, and/or cliched to the point of monotony. The opposite of new hotness.

Old and Busted: Britney sucking face with Madonna.
New Hotness: Janet Jackson flashing at the Super Bowl
