Chinchi scoots on wet towels

So, this isn’t an issue really, more of a query as far as behavior.
My chinchi, Chinchi, will scoot her butt on wet towels. Any wet fabric really... and when my mom was chinchi-sitting for me, she twice shot piss after encountering a Diet Coke and then a glass of wine sitting on the floor with my mom. It’s like she is a weirdo with liquids... is this a thing for anyone else?
Thanks!
Sincerely, Chinchi
