Reverse Grenade

Crazy woman. Doesn't explode until you stick your pin in it.

Slide your fist into someone's asshole and spread all your fingers out all at once.

Much like the regular hand grenade, but instead of using a vagina, you are using an ass hole.

It is described as the act of pleasuring a women with the use of one's hand. The act as described as "devastator" is to make a fist and insert into the woman's vigina, the next act of the "grenade" is to quickly open the hand so the fingers are spread as far apart as possible while still inside the women, the final act of the "reverse bear claw" is to curl your fingers (as if you're scratching a person's back) and quickly pull out.
