blazing motherfucker 

A masochistic or malicious sex move (depending on the user's intent) performed by the posterior partner having intercourse with a person from behind (as in the doggy-style or reverse-cowgirl positions) and smoking a cigarette at the same time; after climaxing, the posterior partner burns the anterior partner's back with the cigarette, pulls out and leaves (while still smoking the cigarette) before the anterior partner has a chance to climax.

I gave Jenny a blazing motherfucker last night. She was so pissed! She ended up with a nasty burn on her back and didn't even orgasm.
