The act of a man shitting. Then while shitting, a female climbs on the mans lap facing him and begins having sex. The man spreads his legs allowing a pathway, so the women can also begin shitting. A proper Brown Eagle will result in a well timed double plop in the toilet.
Dude, she brown eagled me and clipped my balls on the follow through, I have a giant brown stain on them!

When a girl opens her legs so far that her pussy actually splits in half, and you take a dump in her open pussy.
When I walked in the room the girl was spread eagle on the bed, and i took a huge shit in her pussy."Brown eagle"
