I hate my SO's friends. What do I do?

My significant other is a kind, wonderful, and loving person, but I dread the prospect of ever having to hang out with their friends. They are all extremely closed-minded, loud, obnoxious, and all they care about is drinking, partying, and talking trash. I feel like I have nothing in common with them as I am pretty quiet and shy.

The SO’s friends are often rude to me, make fun of me, and try to pressure me into drinking when I don’t want to. According to my SO, they all think my SO should dump me, though we both disagree.

So I don’t spend time with my SO when they are around their rude friends, but I can’t stop feeling angry and jealous whenever they are all hanging out without me. I don’t know, I guess I’m just mad about this. Is there a solution to all of this? I can’t expect my SO to just stop seeing their friends, but I also can’t stand having to be around them.
