In unicycling, an unplanned dismount. Not a fall per se, but something that causes you to step off or otherwise end up off of the unicycle without any injury or dramatic falling.
Unseen bumps can cause occasional UPDs, but as riding ability increases, chances are you will just have the shit scared out of you.

“UPD” or “Último Primer día” (Last first day) is an argentinian celebration that students make in reference to their last first day in high school.
The UPD begins on a night prior to the start of classes, with the condition of staying awake until entering school the next day. The celebration begins in a house where all or some members of the course meet, which then lasts overnight in parks near the school and ends at the door or in the courtyard of the institution they attend, until the time of school entry.
This celebration is widely criticized some acts of vandalism, the noise late at night, the use of flares, dirt generated on public roads and, especially, the consumption of alcohol

University Police Department. The name of the police department in all of State University of New York schools.
I hate the UPD because they always give out parking tickets for stupid reasons. They should be trying to curb the rape rates instead.
