Why do I get so much mocking over a semi "catfight" in Starbucks*? sexism?

As I have mentioned on here before, hell it was why I joined! Wish I was trolling. So I was in starbucks a couple of months ago, when a girl iknow came in , long story short we had been arguing through different people over her ex who I had been seeing at that time but have since parted ways.
Anyway she was being petty asking to "borrow a chair" I made a comment about her mask, and stood up she questioned my "respect" so I mentioned her love life history, she mocked my tan so I grabbed her hair pulled it to the side for like 2 seconds she then stands on my barefeet and pushes a ull cream cake/pie in my face, a couple of my friends were there and its since been a daily ridicule, they found it "hilarious".
