1: A great wizard who enjoys eating sandwiches, making sandwiches appear out of nowhere, turning things into sandwiches, turning PEOPLE into sandwiches, and racquetball.
2: That one person you may know who is ALWAYS eating a sandwich. It could be a classmate, a friend, a workmate, it doesn't matter. They just always seem to have a sandwich whenever you see them.
"Racquetball? Sandwiches? Wait, I know who you are! You're the sandwich wizard!!"
"He's some kind of sandwich wizard or something...He always pulls a sandwich out of his pocket the second we go on lunch break."
