The point of good communication is to be effective and unambiguous. For this reason I choose to stay away from acronyms until everybody settles on what the definitions are. If you have not agreed to your definitions, then all you will ever argue about is definitions.
When someone asks me what my system/technique is, I say I climb on a doubled rope with a lower-able false crotch/friction saver. I keep the terminal end and the hitch/mechanical device at my saddle. If that doesn't paint the picture, I don't know what acronym will.
