I had a similar problem many years ago, I ended up just suggesting I would beat up my floor manager and I got fired on the spot. I hated this fucker.

Just remember you need the little money and you are only there part time.

Ignore him, but try to see if he brings a lunch and then do things to his lunch, you can use your imagination or do a google on how to get back at co workers with out getting caught but you must NEVER, EVER brag or boast about this to anyone. Keep your little job, so at least you will have something to fall back on later as a resume in the near future for any other part time jobs. Don't get your self fired if push comes to shove, talk to the boss and tell him you are thinking about leaving because you are unconfortable in your dept. You can't biatch and moan if you really suck at your job though. If you are not giving it 100 % then you have nothing to complain about, I guess you are just new and have not learned the ropes all that well. Remember you are only there part time and this biatch is there all day, fuck with his car or get one of your homies to do it for you but no one else must ever know. A fish dies by it's own mouth and so do people who do things and then brag about them so remember, mums the word. All I can say is just let him talk, talk is free and keeping your mouth shut when he says anything will deter him some. Just pretend he is talking chinese or something lol. Don't know what else to say but good luch.
