A sexual position where a woman lays on her back and the man sits on top of her. He sits on her chest and holds her ankles by his shoulders, hence like chopper motorcycle handle bars. In this position he can titty fuck her, get a blowjob/balls licked or sit on her face for ass-licking, hence the brown part of the name.
"Baked Brown Log" is the act of taking a cookie sheet and expelling everything that exists in your bowels onto it and then putting it in the oven at a medium high heat. Then you leave it to bake and fill the house with an aroma that is comparible to a sewage treatment plant on a hot summer's day.
My bitch cheated on me so I left her a BAKED BROWN LOG in the oven cooking for her.
