When holding a longarm/rifle, the act of bending your arm to a 90° Angle to the body, making it look like a Chicken's Wings. This technic is the right way to hold a rifle with a traditional stock, as it provides a sort of grip between the shoulder and the clavicle, however doing it with a rifle equiped with a pistol grip will result in you looking like a dummy.
-Yo Rick, why the fuck are you Chicken Winging ?
-That's the right way to hold a rifle, dumbass !
-You're using an AK platform, idiot. You have a pistol grip and the buttplate is like 90% over your shoulder, you're just being retarded.
