Fiction/Fantasy
Ripping out an old mans teeth for thinking he could "dom" you, splitting his penis down the middle as a precursor to splitting his body down the middle in his own home before force feeding him his own shit from his own intestines while he dies. Then writing "Don't fuck with me old man" on the wall in his blood. Then you obviously get away with it even after you tell everyone so all the other gross worthless shitty old men are scared of you then and they hide when you come around.
Fiction/Fantasy
Hitting him in the head dozens of times until there's a big hole in it, and then laughing to yourself for minutes because he was a hole to people and now he is a hole, because there's a hole where his face used to be.
