Despite looking delicate or feminine or "not punk", a Pit Princess is a girl who dominates a punk push pit or a metal mosh. It's not that she's not in the scene, she just doesn't feel the need to prove it by how she dresses. Instead demonstrating how metal she is by hardcore moshing...ask her for her pit injury horror stories because she definitely has plenty.
Not every girl in the pit is a Pit Princess. If she looks like she belongs, she's not a Pit Princess she's just fucking punk. Pit Princess specifically do not conform to the metal aesthetic and are often judged for being posers or excluded for how they dress - until they get in the pit to prove their love for the music and the pit.
damn look at that girl shoving others in the mosh. I thought she was a poser dressed like that but she's a total pit princess.
