I actually agree with Zapp (Does that make me an elitist bastard? Wait, I already am! O.o).
I know code words are meh, but yeh, sometimes they can save time (if not always) and force ooRP players ask "wut duz rp meen" and we can answer "Read on forums, foo". Harharhar. I'd find it funny to see more abbreviations for other things, which might eventually end up in "abbreviational sentences" (Ever played RF Online? Phrases like "BD 31-35 4/8 LF AoE @ GK" are no rarity there).
