Some lame-ass shotgunner was tryin' to holla at me.

When pulling over a driver for acting like an idiot, you start yelling at the driver, and then:

Shotgunner: "You wanna piece of me?"

You: "Look who's tryin' to be a bad ass. You're just a shotgunner moochin' off other people cuz you're too stupid to drive your own car."

Get the shotgunner mug.
The people who use a shotgun in call of duty. They usually use shotguns because they can't get a kill with a normal weapon. Most people rage when they get killed by a shotgunner even other shotgunners. They almost never aim down the site because a shotgun will spray out a lot of pellets and kill people who aren't in the line of fire.
The shotgunners killed everyone on my team without even having to aim down the site.
