The act of shitty on your partners face. followed up with cumming on it and then punching her in the face. after all this is done you sat you nuts on her head and yell, "Madd Hatter bitch!!" thus making your nuts the hat and your girl pissed.
Luke: i totes gave Grant a Madd Hatter last week!
Lucifer: man i wish you'd give me one of those sometime!
