Penis

In Evan S. Connell's book "Son of the Morning Star/Custer and the Little Bighorn," he makes reference to Indian calendars and the custom of some of those calendars to highlight an event from a particular year. Subsequently, that is how they remember the year.
Connell cites Bruce Nelson for this nugget: In the Miniconjou year of 1796, the great event involved a game of hoops-and-sticks in which a player named Penis was killed. The calendar doesn't indicate how he came by the name, but Penis apparently attacked two players during the game, and they killed him. The game continued, and they used his body as a backstop. The year 1796 henceforth became known to the Miniconjou as The-Year-When-the-Hoop-Rolled-against-Penis.
This particular Penis, apparently, led less than a charmed existence.
