A ruler made out of metal that is inserted into an ass. it is then licked and tasted, and sometimes wiped in other people's faces. It then must be hidden in a drawer in a science classroom for a whole school semester for it to develop into a Michael Heath Butt Ruler.
I found a Michael Heath Butt Ruler in the science lab yesterday. I stole some gloves and threw it into my fire pit.
