Firearms enthusiast mispronounciation of the actual word "ambidextrous", meaning capable of being fired with your left hand if your right hand is holding a cigarette. Acceptable only in the firearms community.
The new generation of Glocks has an ambidextrius magazine release. You can switch it over to the left-handed side for situations where you're drinking bud heavies and might need to shoot your mailbox to prove your father in law that you can shoot.
