Kinda but not really. Mint is OBSESSED with butts and buttholes. She will mention butts, buttholes, or some other word involving them at least once every single stream. I am not kidding.
She always emphasized her butt, even as Pomu.

Dunno if she specifically likes anal, but I think it spawned from that.
The piss thing is entirely separate though. That's just a fetish apparently.
