Someone named Meredith who acts like a real dick. Meredicks can get crazy, but usually are very likeable and sexy when they are not exhibiting dick-like behavior. Sometimes guys will use the term Meredick to refer to someone they would bang.
Guy 1: "Dude, look at that Meredick over there.."

Guy 2: "Daayyyyum!!"
