Replying to Fuck My Rommate

Alright, so roommate is fucking weird as shit.  He is always touching me, creeping.  I woke up to him staring at me yesterday.  The whole floor thinks he is weird as shit.  He is dirty as fuck, theirs literally food remnants everywhere.  I woke up to a half eaten burrito just chilling on the laptop.  He eats my food (he ate my whole pizza last week) and killed my Ben n Jerry's last night, obviously without asking.  He thinks we are perfect roommates.  So I told him basically that I would rather live by myself and he still couldn't take the hint.  So I woke up early and blasted some death metal this morning for an hour, he didn't seem phased.  I then "accidentally" locked myself out of my room after my shower and banged and kicked the door for 5 minutes until the fuck came to open the door.  I can not do this for the rest of the year!

What should/can I do to piss him off and get him to move out?

I can get you some pics of shit that goes down, if necesary
