Rusty Croaker

The act of inserting a frog into a persons anal cavity facing outward, and then inserting your penis into the persons anus until the frog bites the tip of your penis and you can pull the frog out attached to your penis.

I was hanging out with a hooker in a swamp when all of the sudden she asked me to give her a rusty croaker. She said it was like dick noodling frogs in an ass.
