He's probably joking, what troll

Well that's pretty ****** off. I'd probably lose my mind and throw a cocktail of hornets and firecrackers at him in his sleep. Let the games begin, you owe it to yourself to get him back. Who knows what other shit he's done..think about your toothbrush..food..you oughta buy your own food keep most of your hygienic products under lock n key in your room. Maybe invest in some pepper spray and an air horn shit I dunno but good luck OP?

Totally inappropriate thing to say, especially to a sibling. Not weirded out at all.

Well just WTF.

i wonder why the hell anyone would think that OP deserved it?

If you are going to have your own room place a motion activated camera with web access so you can see whoever is in your room. So, you can catch him red handed.

Make his room in your new place the designated chicken chocking room. Have friends over and make it a real party.

this is why FML exists

No, just plain no...

That's beyond concerning.
