National Holiday.

Every Friday, it is the day to wear a flannel.

It also makes your decision about what to wear that day alot easier.

The day out of the week where you wear your favorite flannel on Friday just to be awesome and good looking. It can be any kind of flannel. And it doesn't have to be the same one every wekk

It can also be called FFF for short.
