My situationship bashed his friend for calling me a slut?

Okay so apparently at school today, this guy I’m almost dating was talking about me and his friend came over and said ‘oh is this that slut’. So my guy pushed him, his friend pushed him back and then it turned into a fist fight. Apparently they’re all good and they’re still friends and hugged it afterwards, and he feels awful about it.

Should I be concerned? One part of me doesn’t really mind it because I’m used to my boyfriends friends being disrespectful about me and my boyfriend not caring (and I’ll admit, it’s kinda like those bad boy books). But the other part is a bit iffy.
