fisteldink 

The act of inserting one's fist into another's anus while the recipient is urinating. The term is derived from a "distlefink," a small bird whose call often resembles the noise made by the recipient of a fisteldink.

Dave approached the urinal, dropped his trousers, and began to pee while Rahul fisteldinked him from behind.
