uno 

An activity that regularly occurs within the walls of Washoe Couty Jail (Par). Though, the lucky people who have never been confined to Par, we can only assume it's sodomy on a mass scale.

Josh- Yeah, jail wasn't so bad. My roomate and I played Uno all day long.

Charlie- Um, that's um, disturbing, I hope I never get sent to Par and play fuckin' uno all day.

Josh- It's not as bad as it sound once you take it long enough.
