Does this verb have any currency in modern English?

MW labels it as Scot, with the meaning rebuff.  Had I not looked it up, I would have assumed it was an error conflating rebut and refute (as indeed it may sometimes be).

I can’t say I’ve ever heard of it before.

OED doesn’t have this as a separate entry (as you and the good Doctor likely know). The last use of this verb with this spelling is:

1562 A. Scott Poems (1896) i. 108 As waspis ressauis of þe same bot soure, So reprobatis Christis buke dois rebute.

which may be the MW reference that Dr. T offers.

Okay.
I saw something on Facebook saying that it is “time to rebute”. In context it appears to mean “retaliate” rather than rebut. I thought that it was very likely to be a typo, or some other kind of error by the author, but I thought I’d check with youse.
