A sexual position meaning to take a girl from behind on the edge of the bed. Either Anal or Vaginal. Benificial because the goat will always be pushing back.
Me and my girlfriend were feeling very environmental so we decided to do the goat on the cliff.
A: I want to do it, but i don't want to lose my virginity to you. Thats my only problem.
B: Simple, lets do the goat on the cliff.
