June 22 is 'No Panty Day'?

MANILA, Philippines - Don't remove your underwear just yet, ladies. Social media was on fire Friday after posts from many Twitter users claimed that June 22 is officially "No Panty Day" worldwide. The alleged event was even surreptituously added to a Wikipedia entry on international observance days. One blogger speculated that the event may have been taken from the "No Pants Day" in United States, an ad campaign, or "maybe just a plain joke."
