Usage examples of "chunker".
Rydell heard himself say, slapping a holstered Glock onto his uniform and grabbing his chunker, which aside from its rate of fire was probably the best thing for a shoot-out in a nursery full of kids.
He stumbled forward, cradling the yellow bulk of the chunker, vaguely aware that there was something wrong with his arm.
The chunkers weren’t even guns, not legally anyway, but a ten-second burst at close range would chew somebody’s face off.
