When you have a female friend who is resistant to anal sex bouncing on you reverse cowgirl and you Jam your index and/or middle finger into her ass far enough to hook some of her guts up. The desired effect being that as she gets scared/disgusted and attempts to jump up, she will be unable.
"Yeah that bitch tried to get away, but I hit her with the old Gut Grappler technique I learned in Nam...."
