Term for someone who cannot refrain from passing comments, can't find thread

[WeAreOnTheRoadToNowhere]

There was a thread a couple of days ago by a poster whose mother passed comments frequently. I think she was Scottish. I loved the term she used to describe someone who does this but I can remember it
Can anyone remind me pls

Pass remarkable springs to mind.

Yes, passing remarks = ‘pass remarkable’.

Gob on a stick.

Giving unsolicited advice
