Use of "PR" as a verb

Solution 1:

MetaEd actually answered my question in a comment on 2 Mar by pointing me to a WordReference.com discussion where the OP says this has entered English via Russian, where PR as a verb" has become common:

Can I say XXX (name of the company) donate money to charities, but they don't do it because they are so kind but to PR themselves.

I'm asking this because 'PR' has found its place in the Russian language and we often use this word the way like in the examples above (I mean colloquially).

Solution 2:

Evidently PR as a verb has been around for some time with the meaning of (1) do public relations work and it's not hard to see why it's also come to mean (2) to paper over an issue or problem (i.e., do nothing to solve it) or to BS or even flimflam someone if you are "all talk." I find it strange that I haven't found a formal definition of the verb that addresses these meanings, but will add one if I do.
