Someone who is self obsessed, believes to be better than everyone else, boasts about everything, sucks up to teachers and is just damn right cheesy.
Cheesebag: "Hi sir you're looking great today"
Cheesebag: "Oh yeah I got five A's"
"Oh my God that guy is such a cheesebag!"
Cheesebag: "Oh yeah I got five A's"
"Oh my God that guy is such a cheesebag!"
