I feel so uncomfortable around group of bros.

This is probably because i'm autistic and i mostly talk to women not really with other men, but i want to share it anyway.
Today one of my ex-mates invited me to a pizzeria for old times shake and i said well sure why not, maybe i could use this to teach me how to talk to other men, when i arrived there there were 3 other dudes in the table, i was surprised at first, but i didn't give it much thought at first.
Oh boy, when the conversation started, the "bros" started to throw obscene words that make me uncomfortable like he told another dude "gona piss in ya ass, bro" and it was just gross/weird, they also keept talking about stuff like football and gym that was very boring to me.
NGL, i told them i was feeling sick and left early, i just feel so uncomofrtable to be around those dudes, it seems like it's a popular thing to do in groups of men, but honestly i don't get this "male bonding" thing, feels alien to me, i think it'll stick to women and introverted feeler men like always.
