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."
