The act of one man forcing another to anally penetrate him. Bottom-raping distinguishes itself from ass-raping through its etymology: the partner who is penetrated in gay sex is referred to as 'the bottom'; therefore, having another penetrate you against their own volition is a separate, yet equally terrifying, form of rape.
Jeff doesn't care that the guy he wants to hook up with is straight, so Jeff plans to get him drunk and bottom-rape him.
