You should complain that your vision is blocked and ask to have your seat moved - it'll show you real fast if you have any fellow shitpeople in the class with you and shame the fatty. Plus, it's a fair complaint, it really is getting in your way.
You could also get a little febreze spritzer or something and spray it around when the fatty sits down. Say something like: "That fat..sorry... fast food stinks."
