Yes, I’m using it in the sense @eastgate describes. I’m not aware of the acronym having another meaning—but that doesn’t mean there aren’t expressions using the same initials.
The acronym’s meaning/instant in use is not cryptic and is literally the meaning of the source phrase. It is pertinent when working from memory, and writing in-non-real-time to an audience of (partial) strangers). I learnt the phrase online in the mid-90s and I don’t think the meaning has drifted. I use it to imply that I may be mis-remembering, e.g. because I don’t have the true source to hand. Thus, another person having a different recommendation isn’t starting an argument and tacitly inviting others to choice in with a better/more complete description if they know.
ISTR (I seem to recall) has a similar usage. I think a lot of these acronyms, which are essentially shortened ‘filler’ phrases, date from early online days when everything was slower/more limited . Thus such formalised concision was helpful. I guess the habit has stuck. 
Does that help any?
