The sometimes sexual act of first excreting fecal matter upon someone's chest, Cleveland steamer style, and then urinating into his or her mouth. It can also be an act of disgracing someone that is hated by the person defecating upon the other participant.
1. I knocked Carl the fuck out and then I steam-n-streamed all over that douchebag.

2. Mary loved it when she got that steam-n-stream right on her chest and then a long distance shot into her mouth.
