The phenomenon where a man's penis curves to one side every time he has an erection. Is usually genetic.
Man with a hookshot: I can piss around the corner.
When one person kicks a man in the balls from behind. A true hookshot is done with the tip of one's foot, but any other part of the leg is acceptable.
Dude, did you see that guy get a hookshot? He got it so hard he was rolling around on the ground holding his balls, man!
