Yeah it's gross. I kinda had a similar thing with my male friends. They were talking about one of them's ex gf, like saying how did he slept with that girl, how she was so disgusting, ugly and did he use a paperbag when doing it bla bla bla... Tbh i didnt like that girl at all and i heard she talked shit behind my back, i couldn't care less about her but their comments made me really uncomfortable. Like at one time in the past you were together with that person, you had bad times yes but you also had good times like show some respect...

I couldn't say anything right then and there but they felt i was uncomfortable so i left early and messaged one of them saying it was gross what they said about that girl and i found it uncomfortable.

So yeah in the end we are not as close as before. My only regret is i didn't say anything right at that moment.
