Isn't the idea to be able to discuss this publically, like they all used to do when out sarging or doing workshops, without the target/set cottoning on that they were part of someone running game? Then who gives a toss if it sounds like a video game
But, I definitely understand where you're coming from on this personally; I never use it, because no-one else I know personally deals with Pick-Up.
My cousin is a natural, and you wouldn't think it to look at his large frame, but we peacock frequently and work different sides, naturally. He does this without ever having researched pick-up as far as I know...
Before I knew what peacocking was, I would do it naturally, among other things which have only now been researched upon by me, and explained in the form of these terms and acronyms...
