OODA loop?

Hey quick question. Which one of you knows what OODA loop means? You heard Master Ortez mention it a bunch of times; and I know Master Garr talks about it in both his basics and fighting training. C'mon, you can tell me, I won't tell.

All right. OODA loop is a concept that Colonel Boyd of the USAF came up with, and it stands for Observe, Orient, Decide, Act, and Loop (as in start from the beginning again). Here's how it works:

Observe:
Oh how nice, I spy a foot flying toward my noggin.
Orient:
Let me reflect on what happened last time I had a foot come a-flying.
Decide:
Mayhaps I will get out of the way.
Act:
Duck
then...Observe again. As in, here comes the followup kick....

Problem is, if we don't get to the Decide part in OODA, you get stuck in the Observe-Orient part (i.e. by the time you're ready to act, your opponent has changed the situ and you have to reset and take in the changes, which chews up even more reaction time). Flip side is, if you can enforce you OODA loop on someone else, you can get THEM stuck in the O-O and gain the advantage.

Easier said than done, but that's what it means.

Key point of all this is, if you don't know what somethin' means, do ask! Caveat of course is, ask someone who knows (not me. I had to ask too.).
