No Pants Day is an international 'holiday' observed in several Western and other countries, including MikeK's domicile and office, on the first Friday in May by not wearing any pants (trousers). The use of the word pants is the American English version meaning trousers (the item of clothing covering both legs worn as the outermost garment). According to the FAQ, it is mainly "a fun-filled holiday", but "from the core idea comes so much more":

When large groups of people parade around in public without their pants, amazing things are bound to happen. At the very least, you’ll take your drab, wretched life a little less seriously, at least for one day.

The recommended No Pants Day attire is thick, appropriately modest boxer shorts. Other types of underwear, including bloomers, slips, briefs, and boxer briefs all work as well. In addition to pants, the wearing of other conventional leg coverings, such as skirts and dresses, shorts, and kilts is also discouraged.

History

The history of No Pants Day is shrouded in mystery. While there are unconfirmed reports that the holiday was celebrated as early as 1985/86, there is no known physical record of the origin or first practice of No Pants Day. The Knighthood of BUH at the University of Texas at Austin is viewed as the principal organizer and advocate of the holiday. Austin, considered the originating city, has celebrated the day since 1997 according to a 1999 flyer. The holiday gets media attention every year, and as a result events celebrating No Pants Day have popped up in cities across the globe. Promoters claim that the holiday is really about not taking yourself seriously. It’s an example of surreal humor, which relies on an absurd situation (in this case, crowds of people walking around wearing no pants).
