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.

Man my chick was bitching like crazy yesterday. Its ok though because she pulled a reverse praying mantis

Reverse preying mantis 

A reverse black widow or preying mantis is a male that kills a female after they mate.

Henry VIII of England was a reverse preying mantis since he would chop a female's head off after they mated.

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.
