Unlike what some people may believe, a half cock is the position of the hammer of a firearm when about half retracted and held by the sear so that it cannot be operated by a pull on the trigger.
Person 1: I didnt realize I had it on half cock until I tried to fire.

Person 2: You dumbass, you gotta pay attention to that shit!
Get the Half Cock mug.
