when a man cums into a girl's mouth, and then lies on his back while she squats over his mouth and takes a shit into it. He ingests the cum-shit mixture. If performed to completion, he will "boomerang" the cum-feces mixture back to her mouth in the form of vomit.
I met a lil' slut from Livingston Parish, she loves the ole Baton Rouge Boomerang
Get the Baton Rouge Boomerang mug.
