I know she means she OK, but what is 5x5?

Something to the effect of "All Good"

It is some kind of slang that pilots use when flying, I think.

I could explain better if my brain was working properly. Sadly the new episode of Lost has killed it.

The meaning of "five by five"

The "Five by Five" comes from military radio operators who used the phrase to tell the person they were talking to how well they were coming in. There was a five point scale in two categories, strength of signal and clarity of transmission. A strong, clear signal was coming in "Five by Five", lesser signals would be judged with lesser numbers. Radio operators and other servicemen picked up the phrase to represent generally good circumstances. So when Faith says everything is "Five by Five", things must be, by her standards at least, going great.

This phrase is also used in the movie Aliens and the lot's of videogames.

I knew it had something to do with radios...I just thought it had something to do with truckers (don't ask me why).

My dad's a ham radio operator (second-generation geek, here!) and I heard 5x5 a LOT as a kid. The first number quantifies signal strength, the second signal clarity, on a 1-5 scale, with 5 being the best. Thus, 5x5 = "I understand you perfectly" or, in Faith-slang, "It's all good."
Hearing Faith say 5x5 made me grin! I also got nostalgic fuzzies from the computer-generated voice counter on the repeater when they picked up Danielle's signal. My dad played with his radios in the basement at night, and I would often hear him through the vents, along with Radio Mexico, or whatever he happened to catch that night. "1...6...2...4...9... repeater." I pretended he was a spy intercepting coded messages and saving agents and stuff. Wow, that was a ramble! My geekiness shows itself often at inopportune moments!

Thank you all, I'll be able to sleep at night now. That has bothered me since I first heard her say it.

....now if you guys can tell me the meaning of life, I'll really sleep like a baby at night ;D
