A hideous, debouched, grotesque, sex act, in which a man lines his anus up with a woman's vagina, and proceeds to defecate into it.

Some may even go the extra step and continue to penetrate it feces plugged vagina with their penis.

Very difficult to accomplish, and only the most hardcore may even attempt it.
Man 1 - "Oh man, last night I gave my chick The Notorious Brown-Frown! She was all about that!"
Man 2 - "Wow, you're a disgusting man, I must now strike you in the testicles with the tip of my foot."
