Anyone over the age of thirty that faithfully watches and gets overly excited about the show "Glee".
Dave: "Dude! I can't wait for tonight's show! Brittany is doing Britney! I'm Gleeking out! Can I hang out and watch the show in your room with the other Gleeks? I'll make the popcorn!"

Ariel: "DAD! GROSS! You are such a Gleezer! Why don't you get a grip and go watch Dancing with the Stars in the living room with Mom?"
