Autism inbound:
That's sounds like such a larp.

I played hockey for years and that reeks of
"No one can disprove this with a video so I'm going to try to sound cool" bullshit. Firstly, and granted female shoulder pads/chest protector
(which also cover most of the torso and are strapped around your back rather than just hanging inside your jersey loosely) equipment is a little bit different I'd assume, between where it covers the body and having a jersey on over top of it, it would be very hard to get your hand in while fighting someone (ESPECIALLY while they're wearing a fucking jersey) to tear out a navel piercing.
Secondly, if you were really "repeatedly punching" someone in the face you'd be stopped pretty quickly by a referee, especially if you're playing some house league shit (which she would've been.) It sounds like she's trying to sound cool to a bunch of American teens who think that hockey is actually like the movie
Goon or
Slap Shot where you're just allowed to be absurd and there are 90 fights and instances of CTE per game. No, tearing out someone's piercing is not
"just what you did." You'd be kicked off your team so fucking fast, without your parents getting their money back. That was not some sort of agreed custom or something that happened.
And if we assume that this wasn't during an organized game or something and just some horsing around on a pond, I'm going to smash X to doubt on that because firstly: it still sounds ridiculous coming from Anisa, secondly: I doubt she's ever even fought anyone, and thirdly: she's probably never played outside of organized indoor hockey (not even shitting on her for this last part, plenty of people haven't.)
