>they are too poorfag to buy their own headset so they will want to borrow mine all the time to play gay saber and whatnot and now and i can't say no or i will be the asshole everyone hates ;_;

Make your face gasket nasty. Take off your cover (if you have one) and let the foam get filled with hairs and grease. Show it to your flatmates and say they'll need to buy their own cover or it's like rubbing faces together. They're poorfags, they won't do it.
