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.
My girl has been pissing me off by hitting me in the nuts by "accident" so I decided to giver her the ol' devastator, grenade, reverse bear claw (DGRBC) (DGR)
