These Pictures Of People Celebrating 'No-Pants-Day' Are The Very Definition Of Swag

"No pants are the best pants."

When people decided to drop their pants for the revered 'no-pants-day', I'm sure onlookers often bump their heads here and there, amid all the ogling. The tradition started in 2002 by a comedy group called Improv Everywhere and gradually became a worldwide sensation.

A lot of people around the world can now be seen wearing no pants and pulling off funky boxers and underpants. Some call it cool and some call it fancy, but we call it ballsy.

Check these out!
