Half Cock

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!

Peter: "I doin' the best I can do with what I got, bay-bee!"
Laila: "T'aint enuff, BAY-BEE!"

Mission and a half

A task so prolonged or difficult, it seems as though you're taking on more than you bargained for. Once completed, you feel so irritated (or relieved, depending on the situation) that you can't help but talk about it to someone.

Sophie: I didn't get picked up yesterday afternoon and had to walk home. It took me two bloody hours!

John Smith: That must've been a mission and a half.

Double-half.

A variation of sexual intercourse enabling the male to give the female double the girth but only half the length. This is achieved by going in with a flaccid penis folded in half.

It was like throwing a sausage down a hallway, so I gave her some good old double-half.
