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!!

you stick your finger in your own butthole, and then walk up to your victim and put the the same finger (in the shape of a fish hook) into their mouth and the inside of their cheek. Then pull like you are catching a fish.
He pissed you off? Give that dude a rusty fish hook!

A rusty fish hook is when you stick your finger in your own anus and curl that finger and put it in someone's mouth and pull outward.
