Derived from the term TGIF (thank god it's Friday) along with special thanks to the annoying new hit single by Rebecca Black, the term refers to the moment you think about 'Friday' the song, when you realize it's Friday.
Bob: Hey John! can you believe it's Friday already?

John: *It’s Friday, Friday. Gotta get down on Friday. Everybody’s lookin’ forward to the weekend*

Stands for "Freezing Index Finger Syndrome" Usually occurs around October when the weather becomes colder. Inflicted by constantly playing handheld videogames where your index finger is alone and cold.
Person 1: "Dude, what's wrong with your finger?"

Person 2: "I couldn't stop playing Birth By Sleep last night, and now I have FIF Syndrome!"

First you have to FIF THE WIF how you FIF THE WIF is quite easy, you have to have your arms and legs in a hoodie and waddle around. Then to WIF THE FIF you have you go up to another FIFER and WIF their crotch.

After you WIF the crotch of the FIFER you have to do the sacred ritual to WIF THE CLIF how you do this is you have to jump off the cliff and beelieve you can fly

Now after you WIF THE CLIF you have to WIF THE DIF how you WIF THE DIF IS bit harder than FIFING THE WIF

To WIF THE DIF you have to die after you fail at WIFING THE CLIF you, you soon learned you did not BEElieve hard enough......

Ok after you realized you didn't BEElieve hard enough you turn into THE PIFER after you die you get reincarnated into a magical singing dragon named PIF

now you have BIF THE FIF you have to find another FIFER after you turned into a PIFER and BIF the FIFER to do this you bright (bite) the FIFER

After you BIF THE FIF the FIFER should bite you if not then you lucky... When you die from the FIFER that is called NIF THE FIF that's dieing of a FIFER
