chopper (commonly pronounced choppa) is the nickname for the Thompson sub-machine gun a.k.a. the Tommy Gun. The word is derived from the sound it makes when being fired in full automatic mode which makes a chopping sound. The word is now used in pop-culture particularly in rap music to describe any kind of fully automatic sub machine gun.

I went to the gun show today and picked up a nice chopper.
