The reverse of the name "Fred". Commonly used by people who are either trying to be silly, those who think that it's a cool name and didn't like being labeled a "Fred", and those who truly think that it's a great pseudonym and no one will ever figure it out.
Overheard at a trekkie convention:
Fred: "Dude, I'm so awesome, I'm gonna reverse my name and call myself Derf."
Clueless friend: "Dude, that's awesome!!!"
