Bum Tumbler 

A pejorative term used to imply someone enjoys sticking their fingers up someone else's anus, most commonly used as a gay slur. The name comes from pin tumbler locks as you need to stick a key or pick into the lock to move the pins to open the lock. The finger would be the key and the ass is the lock.

What're you Bum Tumblers up to?
