Brag: I pwned my gf's bitch ass roommate

[saucyspade19]

So my gf has been living in a house at school for a few years, and she has a random roommate this semester for the first time. He is a conservationist, "al gore" type liberal who always turns off the air conditioning, and turns off the lights when she is in the room, and emailed the landlord trying to welch on his percentage of the cable bill because he "rarely watches tv." This kid is the biggest vagina ever, and I've had to hear about it all semester.
Tonight we got back from drinkin at the bars, we come in and the house is hot as hell, we turn on the a/c and he comes in and says "I don't see why this has to be on" and turns it off. I say "dude, it's hot as hell in here, the a/c needs to be on, I'll pay for it" and toss a 20 at him. He is like "I don't want your money, the a/c doesn't need to be on." Arguement insues, he asks me where I live, calls me a rich boy and talks hilarious [censored], my gf is crying and I almost kick his bitch ass, but I decide he will probably get me arrested, so I take my gf to a hotel instead.
I am considering sticking the bill on his door along with a hundo for his poor ass, but what do you guys think? What is the best course of action to pwn this bitch? I could easily kick his ass, but he is the type that would try to ruin my future by getting me arrested, so any good ideas?

cliff notes: gf's bitch roommate is a conservationist pussy and turns off the a/c, help me make him look like even more of an idiot.
