I was insulted today because of my IBS

I felt the stomach rumbles when I was one metro station away from my workplace (a hospital), I spedwalked into the nearest bathroom, did my IBS-D thing as quietly as I could (there were two other people in the bathroom) but I couldn’t control the smell, and then I hear a lady say, once we’re alone: little slut. She said it two times, to make sure I heard it!

Has anyone else gotten insults like that? It really ruins a day, I was already scared to shit my pants and now I get insulted too!

Edit: the words she said were petite cochonne, literally meaning little female pig, which translates to slut. She was an old lady that was looking at herself in the mirror when I came in.
