When a woman/man deficates on his/her partner and simultaneously slides his/her body up to their partners face leaving a trail of feces in their path.
Kevin, I had Maria give me a rolling brownout last night. There was a trail of shit from my chin to my chest.

When your banging a girl from on top, and get off and proceed to jerk as if to nut on her face, when your quickly turn around, and surprise her with poop instead!
I did a rolling brownout! "How?" While banging your little sister, she thought I was about to finish, I hopped over to her face, and when she shut her eyes SPLAT!... crapped all over her face.
