When you're doing a girl in the butt from behind, you reach over to the nearest fire source and use it to light her hair. Then when she is running around the room screaming, spray her with a fire extinguisher.
Why are you covered in all that white crap? And where's your heair?

My boyfriend did A St. Elmo's Fire to me last night.

Oh, thats awesome.
