cheesehead
1. Someone who is dumb or stupid. Did you hear that guy's ridiculous question? Geez, what a cheesehead. Ah, she's just a cheesehead. Don't listen to the nonsense she spouts. Geez, he keeps pulling on a door that's clearly marked "push"—what a cheesehead.
2. Someone from the state of Wisconsin (which is known for producing a lot of cheese), especially a fan of the Green Bay Packers football team. (Their fans commonly wear novelty headgear shaped like pieces of cheese.) Of course he thinks the Packers are going to win the Super Bowl—he's a total cheesehead. Yep, I'm a cheesehead—I was born in Wisconsin. Those diehard cheeseheads are delusional—this year's team is on the road to nowhere!
