When your fucking a girl and when you feel a fart cooking up you turn her around and stick her face in your ass and fart making it sound like a broken car horn.
Art: "Last night I felt a huge one cooking up so I gave Tonya a broken car horn."
When you take a shit in a sock and swing it around like a slingshot and whack your friend or foe in the face.
Scotty: "Duude Farris got Black Mudpunched last night at the campout".
