A vaguely menacing sexual act, referring to any number of possibly degrading maneuvers. Generally, the act refers to the lesser known, but largely more perverse, sex moves. A grambler is a dominant role, and as such is usually reflected as the male participant. However, females are not excluded in having the ability to gramble. The recipient of a good grambling should feel simultaneously ashamed and satisfied. Origins are derived from the city of Grambling, Louisiana.
"Dude, I don't know. Last night was weird. I took this girl back to my room and we spent two solid hours grambling. I have never done, or heard of, anything this grotesque before. I mean, I stuck my nose in there. God, I need a therapist. I hope I never see her again."
