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.
It took Drew forever to convince his girl to try the brown chopper - sick bastard.
