Rusty Willy 

After stimulating a girl with a finger in her anus... then sticking it in her ear just like you would a "wet willy".

Sally: Tom totally gave me a rusty willy last night. Then I made him play the flight of the bumble bee on my rusty trumpet.

The resulting crusty substance which tends to get embedded into carpet after an older gentleman gives a reach-around to a dog.

I know your grandfather was giving a reach-around to the family dog because this morning I stepped in the rusty wiley.
