A national holiday usually celebrated in australia on May 5th in which you wear no pants or shorts over your underwear.

I was pimping down the streets all nonchalant on May 5th when i saw someone with no pants and realized it was "no pants day".

no-pants day

1) a day to stay in doors and relax in one's pajamas. 2) 24-hour period with no responsibility.

We stayed at home and watched movies all day...it was a wonderful no-pants day.
