Similar to the Dirty Sanchez. While pounding your girl(or guy, whatever your pleasure), you rub and make slow semi-circles around her asshole and the without warning you JAM your finger
in her ass. When she turns around to yell HEY!! you give the ole' fish-hook. The shit on your finger
resembling rust on a hook. You can go for the Double Rusty Fish-hook, but you need to stick another finger
in your own ass right before you jam it in her and then WHAM-O!
Dude, I was railing the chick the other night and she was moaning so damn loud that I had to give her the rusty fish-hook just to get her to shut up...
