Cleveland Stanley Steamer 

The sexual act of defecating onto the top of your partner's head and then proceeding to smear it across their hair using a clothing iron, leaving several smelly burn scars.

Stanley: Dude, I totally gave Cindy on of my patented Cleveland Stanley Steamers last night.
JG: Bro, that's sick! Call the Rug Doctor!
