Has anyone interacted with this person before?

First of all, Happy New Year to all! Me and my partner were walking through Newington when this lady started shouting abuse at us. Completely out of pocket and I've never experienced anything like it from my 3 years living here. She was about 5ft 7, had a long puffer jacket on and was walking a small curly haired white dog. I was wondering if anyone has had a similar experience, as it really shook me and my partner up.
