Someone who was a dildo when you first met or heard of him and has done nothing in time since to make you think otherwise.
You know that John Mayer has been shooting his mouth off about Jessica Simpson. I didn't like the guy when he first came on the scene and I don't like him now, he's a stildo. Or...That guy was a dildo in grade school, a dildo through his teens and after all this time nothing has changed-he's a stildo.
