When having sex in the doggy style position, you pop your index finger in the brown hole, then pull it out and insert into the receivers mouth. Very similar to the "Fish Hook" which is the same thing without the "rust".
So last night i was with this girl i met at a bar. One thing led to another and we ended up doggy style at her place! I thought hey, Fish Hook!! But the finger is rusty? So i did it anyway. Hence Rusty Fish Hook!!

while having sex in the "doggy style" position, you then take one of your index fingers and stick in your partners anus and then hook the corner of their lip with the same finger.

When you hump doggy-style and after putting your index finger in her butt you stick it in her mouth and pull her cheek.
Amazing way to end up with an angry girlfriend. Stick your finger in her butt, then pull her cheek. She is a fish. You are the fisherman. You control the rusty fish hook.

Derogatory sex position: The act of sticking a finger in the butt of a women during doggy sex,reaching for her face and hooking her mouth like a fish. Possibly originating from a man obsessed with fishing.

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...
