Replying to Rainbow Gathering Vagrants Not Leaving My House

Right now I live with two girls and I have respect for both of them although I am not sure what my roommate was/is thinking, when she went off to rainbow gathering.

(For those who don't know what rainbow gathering is. Its a hippy festival with no currencies, ohm circles, and a bunch of hippy drug adventures. It takes place out in nature far from civilization)

In the beginning of July my roommate left to this festival and two weeks ago she came back with TWO RANDOM GUYS. They look raggedy as fuck and they smell like piss, shit, and B.O. We told her not to bring them back because we don't know them.

Now all my weed is being smoked by these guys, they drink my beer and my roommates "boyfriend" leaves all his bullshit out and never cleans up. My roommate wants this guy to move in and apparently she told him he wouldn't have to pay rent. The other roommate and I said that they need to leave, and they haven't.

This guy isn't going to leave if he gets free food, pussy, and a free god damn place to live. I have tried to talk to these guys and my roommate just gets in a bitchy attitude.

Today I came to the idea that my roommate has herpes on her mouth and I told her today and she is trippin. She is at the Dr. right now and she had a sore on her lip.

How can this situation be taken care of? Im sick of this shit. These guys have been living in my house for two weeks and I have to pick up after them every damn day. I just called one of the vagrants out to take a shower it was that bad.
