The most amazing boy you'll meet. He will have cute blue eyes and curly brown hair to go with it. He can make you laugh on your darkest days, and make everyday worth living. He drives crazy but you don't mind it. He is strong and likes memes. If you ever meet one, youll never forget them. This boy will steal your heart the moment you see him. He knows how to make his girl happy.
"Man his hair sure makes him look like a Quinlan?"

"Only a Quinlan would drive a bright orange dodge caliber."
