Flatmate bastard git kill/ignore dilemma

A little while ago there was a thread about people listening to their stereos after 11 pm or so. This is one of my wee vices, but I never have it on too loud, only about a quarter of the way round the dial or so, because I don't want to piss people off, plus which I'm not too keen on excessive volume myself. As such, if anyone complained about it, I would turn it down or off entirely.

Or at least I would have done before last night. My housemate has one of his mates over for the weekend, and they came back drunk last night while I was sitting up in my room, fiddling about on my laptop because I couldn't get any sleep. I then hear someone yell "WANKER mates!" My interest gets piqued a little, then they come up the stairs. They continue to talk about what wankers and losers we are. They then go into another of my housemates' room. This one also listens to music after 11 PM, except at an awful, awful lot louder volume than me. The music he listens to will also tend to be a bit metal, American Head Charge and such and such. This admittedly gets a bit annoying. My housemate then starts talking about how he's going to beat the fuck out of him at the end of the year for waking him up with his loud music at 2 AM so often. He then 'rips the cable out' of the man's stereo which, as I found out indirectly this afternoon, has bugger-all effect on his ability to play American Head Charge at intensely irksome volume.

Then they decide to get started on me. Housemate's mate gets a guitar and decides to improvise a song about me and how I'm ugly. This is not really much of a revelation. Then he does the whole, "ah, you're a faggot, you do small children up the bum" thing. This gets repeated for a bit, then my housemate decides to say something like, "Will, you're an ugly cunt, you'll never pull a fit bird, your taste in music is shit, and if you ever wake me up with your music again I will beat the fuck out of you."

Now, they did this outside my room, and they didn't know if I was in there or not. Then they noticed the lights were on, so housemate's mate opens the door and I go to meet him. I explain that if he was pissed off with me having my music on he could have told me in a slightly more polite manner. He replies, "yeah, well, fuck you."

And that got me mad. I turn my lights off and try to get some sleep, all the while the two of them talk about me being ugly, then about how some 'fit bird' he didn't pull reckons I'm a 'fucking weirdo'. Thus he draws the conclusion that I don't deserve to live, and am an example of why Hitler had the right idea etc. etc. They bang on my wall for a bit, then fall asleep but manage to keep me up for the next hour, because his mate snores.

I wake up this morning and they're prattling on about me and the other housemate again, mixed with talking about fingering Tess Daly and how all gay people are crap at sports. they also find the name Shandeep hilarious for some reason. Then they sod off into town and I get out of bed.

Now, the problem is this - these two are thick. However, they also happen to be a lot bigger and harder than what I am, and I'm a bit afraid of what might happen if it happens again. I could ignore them, but I was so pissed off by that twat refusing to accept my apology that thoughts about how to get revenge on the fucker have occupied my brain for the whole day (aside from a brief interlude of "I should get some washing up liquid"). I have to live with him till June at least. I've thought about glue gunning his door shut (too extreme, possibly criminal), playing music at irritating volume (most likely I'll get beaten up again), or making myself look just like him and aping his musical tastes (Vanessa Carlton-The Calling-Enrique megamix. No). It's seriously irritating, and I'm just afraid it's all gonna kick off...

P.S. if there's anyone in the Selly Oak area what needs a housemate for next academic year, do please let me know.
