In programming, F00 is what you call a variable with a vague name in which you store a color.
#F00 is the color code for bright red in simplified rgb hex. Foo is a variable name chosen by lazy programmers who can't come up with better variable names.
Plural: f00s
Verb: f00ing
Person 1: I just made this javascript code:

var meh = "#FFF";
var iCantThinkOfWhatToNameThis = "#BADA55";
var F00 = "#F00";
var bar = "#123456";
Person 2: Stop f00ing your code up with so many f00s.

Derived from computer music (tracker) code. The "f" represents speed and "00" means that the song (actually pattern) stops.
So basically there's also my redefinintion for the rock band Foo Fighters... I don't think they're "fighting the fools", but rather "fighting to keep the music playing" or something in that direction ;)

More from Urban Dictionary
West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
Some grebo passed with Sabbath playing on his stereo.
The Poppies are at no. 17? God, a grebo band in the charts!
They're playing nu-metal now, bloody grebos!
