<human>: Provide a brief overview of the text.

I need help on how to speak to my roommate about his disruptive and inconsiderate girlfriend. 

Background:
I live in a three bedroom apartment. My partner and I share a room with the other two roommates having their own rooms. We all get on really well when it's the four of us. Now both of them have SO's but my one roommate who I'll call Mike is dating one of the most aggravating people I've ever met. When she comes over, he becomes cranky, confrontational and generally moody. She is loud, ackward(which I know I can't fault her for) and rude. They're both young but fucking Christ, it seems like basic courtesy flies out of his head when she's around. They're really loud, up much later than all of us (who have 8am classes) but still talking as if... well a fucking music festival is going on. She yells all the time. They have obnoxiously loud sex that has woken everyone up, don't do their dishes and are hell bent on occupying common areas kissing, making out and being generally nausauting, even when they're just eating dinner. It makes the three of us uncomfortable. She's done a bunch of shitty things and I've spoken to her to cut the shit but she's either super dense or disrepectful as fuck. She is not welcome here as far as I'm concerned. She's here 4-5 nights a week and lives fucking 10 minutes away. How can I communicate this to my roommate that we can't have her here as often.
<bot>: mostly everyone in my apartment is sick of roommate's Girlfriend and want her to be here as little as possible because she sucks as a person.
