When you acquire a chopper gunner in call of duty and proceed to insert as much of the controller (handle first) into the anus or vagina of a female lover, using the chopper-gunner-caused vibration as a vibrating-dildo-like sensation. This is known to cause the female lover to grunt with pleasure, hence the name.
The motivation from my girlfriend to give her a chopper grunter has increased my motivation to get chopper gunners, therefore increasing my gaming skill, win-win.
