rusty gravedigger

The act of shoving car keys into a persons rectum. Often used as punishment or torture, however, some people find this enjoyable and do this simply for fun.
On rare occasions this has been known to be performed with piano keys.

"Hey baby I to get real nasty with you, got any ideas?"
"Yeah, I want you to shove something in my ass!"
"Oh, you mean a rusty gravedigger?!?"
