Reverse Back To The Future

A sex move when the a male is fucking their partner doggy style, during the act the male or top must be clenching whiskey in their ass. When they are about to come they must release the whiskey at high speeds while holding a lighter to their rectum, this will spray a line of fire behind the performer.

This is in reference to the scene where Doc Brown tries to fuel the DeLorean with whiskey as well as the fire trail the DeLorean leaves behind when traveling through time.

I just did a Reverse Back To The Future on my girl, my house may have burned down but the rush was great!
