(No one has gotten this right yet!) An official "cleaveland steamer" is shitting on a girl's chest while receiving head, plain and simple. Now, there are certain ways to tweak the technique if you will. For instance, you can be having sex, and right before you're about to cum you pull out to put it in the girl's mouth, and then as you're cumming take a shit on her chest (bonus points!). It all depends on how creative you wanna get.

Is where one person defecates on another persons chest, then sits down and rocks back and forth, like a steam roller.
"Things were getting hot and heavy in the Japanese fetish parlour, one of the masseuses gave Kow Chung an extra dirty Cleaveland Steamer."
