reverse Praying Mantis
OK...we all know that a female praying mantis bites the head of the male after the have sex. So a reverse praying mantis is when your wife/girlfriend bitches at you "biting your head off". Then later when she has cooled down and horny she wants to have sex.

Reverse Praying Mantis
A male who has sex with a female, cums inside her, and then bites her head off and eats her entire body for sustenance.
Bro, we were stranded on that island for years. Once we ran out of food the only thing I could do to her was the Reverse Praying Mantis.
