An event that occurs every Friday, regardless of weather, where everyone is required to leave their pants at home for the day. The origins of No Pants Friday (NPF) can be traced back to a cold Canberra night (or two) at Nightsbridge, and first afflicted a group of hearty ANU students. The phenomenon spread like wildfire through the Chemistry department, eventually taking the Fenner school with it. With each Friday, the word spread and more and more men and women join in the NPF festivities.
Mel, it's No Pants Friday, get your pants off and get with the program.

A tradition started by those rebelling against business casual friday. Bad-ass business suits and dark shades are preferred, but anything dressier than your Monday-Thursday apparel will work. Bonus points if you can take your dog for a run while wearing your fancy pants.
The Llama - "What's the suit for? Do you have an interview today?"

Me – "Nah, man. It's just Fancy Pants Friday!"

Adrian – "Hells yeah, FPF, baby."

The day always falls on the first Friday in April (this is not negotiable). The weather does not matter, the day must go on!
One's ankles must be showing. What one chooses to wear to display their ankles is left entirely to the discretion of the individual. Eligible participants include anyone.

If the weather is still cold, it is meant to prove that hope will prevail regardless! For those who have the joy to already be frolicking through warmer days, it is meant for the simple joy of celebrating their fortune in that warmer weather.
Happy Short Pants Friday!
