The act of shoving your fist into your girlfriend's ass down to the shoulder, then picking her up and wearing her like a glove, then slamming her to the floor and quickly pulling our your arm in order to rupture her colon, then beating her mercilessly until she is dead. (This will not work with a wife. In addition, you can not have sex with her dead body or your penis will turn into cabbage.)
Girlfriend: "why didn't you fucking do the laundry like I asked you to you fucking lazy fuck?!"
Boyfriend: "Bitch! I'm going Full-auto on you!"
