format C:\ 

Format C: or Format C:\ is a command in MS-DOS. When you type this command, the C drive of your Hard Drive will be reformatted (to FAT32), meaning that all its entry will be deleted. No virus, program or data can survive this deleting process, unless you can back up the file. If you got this from someone, first of all, know that this person has been working with computers for a fairly long time. Second, is the meaning of this phrase; It means "everything that I remember from you is gone". It can be in a good way, like deleting all the bad memories, and it can also be in a bad way, of deleting all the good memories. Since drive C usually carries the temporary data, it can also mean "the recent memories are deleted". That could be stuff that you load into your head for a test in a single day.
But dont use it in your daily life, this is not really a common phrase and is usually used by computer nerds. This is just for you to understand the meaning and the concept of the usage of this word.

Example 1:
- lets start over again :) heh
- Format C:\

Example 2:
-Ah man I memorized the whole book for today's test. i guess imma do ok.
-heh, yeah...um, what was the answer for number two?
-I dunno, not anymore.
-heh, how come?
-'cause when Im done taking the test, I just go like..."Format C:\"!... I just forget about everything I memorized so I can get ready for the next test.
-you kiddin?!
-I swear!

*laughter*

Format Fuhrer 

A Format Fuhrer is akin to a Grammar Nazi.

On posters (motivational or otherwise), having the correct format is essential (picture surrounded by a box, with the Caption and Subcaption below).
Format Fuhrer enforces the law of correct format, and usually has a few words to say.

*sees picture without a box around the picture*

Format Fuhrer: Format fail, GTFO!

Creator: WTF it's fine!

Admin: He said GTFO, bitch!

format war 

Refers to a repetitive series of hot-headed and destructive actions whereby two or more people seethingly format a computer-disk or other media-storage device over and over to erase the previous user's files because each person either dislikes/disapproves of the content that the other users are storing on it, or each person selfishly/arrogantly feels that his own files are more important/necessary/virtuous than those of any of the device's other users.

I always bring extra floppy disks and/or flash-drives with me --- and clearly label them with my name --- to store my own files when I use the office computer, to hopefully avoid any format wars.
