Much like a Cleveland Steamer; the act of shitting on one's sexual partner's chest and proceeding to smear it around in a circular motion with one's ass cheeks.
My girlfriend let me try the Steamy Roller last night. You couldn't even see her under the three feet of shit I flopped on her chest. She looked like a shit demon when I was done smearing it everywhere. Best night evar.
