Batty Princess

A girl who has lost her anal virginity to a boyfriend or friend with benefits , who now only, or mostly wants to engage in anal sex, in contrast to vaginal sex.

(Batty meaning "butt" in the United Kingdom", in which the word originates from, and in turn, contributed to the creation of the Batty Princess definition).

Guy 1: So how's your love-lfie been with Sarah?

Guy 2: Umm it's alright, it's just that ever since I first done anal with her last week, that's the only thing she wants to do, and crave. It is like she has become some bumsex psycho, literally a full on batty princess.

I'm tired of the stink, I'm just gagging to swim in that clean pussy instead of living within the her shit hole.
