I used to work at a school that was really big on acronyms. Some got so unwieldy that they were just funny. I remember that one genius came up with one for briefing approaches that was something like MMMAILLMANN. No joke. I don't know anyone who actually taught it.
Somebody in my company's training department actually came up with some forced departure briefing acronym at one point. What was it? You guessed it: CAPE AIR. Clearance, altitudes, possible emergencies....yeah, that's about all I remember of it, and I could be wrong about those.
Guess who used it? Nobody. Even the check airmen didn't know it or care enough to use it. If you were caught briefing CAPE AIR outside of a training event you were automatically branded as "that guy." Even in the training event, it was permissible and downright expected of you to stumble through it and give it lip service. Anyone who knows it cold and briefs it perfectly during a training event is also branded "that guy."

Random acronyms are
okay for initial students; for professionals, it's downright unnecessary and dare I say, a bit amateur. Sorry.
If you must, keep acronyms simple. I've personally taught "ABC" when teaching someone to prepare for an approach.
A - ATIS
B - Brief
C - Checklist
As for the actual brief, I never had a student have a problem with a simple top-down brief. No need to get crazy with acronyms about identifying the localizer, etc. Reading the frequency off the plate should prompt you to ID it. Just walk through the approach step by step as if you were going to fly it (duh!

). Start at the IAF, finish at the MAP. Brief the missed, and brief which way you'll turn off the runway. A basic taxi plan is great too. I'm just a simple line pilot who'd be breaking rocks with other rocks if I wasn't flying airplanes; gotta keep things easy.
