Brownback

The upchuck of fecal matter on to your partners back during and after vigorous anal sex via doggy style, wherein the feces propel from the recipients anus due to harsh manner of penetration, stick to the anal givers torso, and rubbed along the recipients back due to the nature of doggy style.

"I was giving Kansas Governor Sam Brownback some good anal until he brownbacked from my force; I instantly came."

"That's disgusting."
"What, the vigorous anal sex resulting in the propelling feces?"
"No, Kansas Governor Sam Brownback. I gag whenever I see his smug, homophobic face."
