Rusty Keyhole 

An obscene sexual act in which sand is used as lubrication during rough anal intercourse. Works best with the world's finest sand -- found on the Gulf Coast of Florida, especially in and around the St. Pete Beach area.

I took my girl out to the beach to see the sunset, and then gave her the rusty keyhole all night long.
