Same goes with your theory about who Dipper can trust, somewhat. I doubt that he will turn to his parents so quickly, we barely know how they feel about their children anyway. Dipper is embarrassed about his birthmark. We also know he wants a different name. So if he has another name, why doesn't he use it? The only two explanations I can think of are a) his real name IS Dipper, or b) it's something even more embarrassing. And there's no way it's Goober. As Doug MacKrell pointed out, Goober is a lighthearted insult. Basically, it's a Disney-friendly way of saying "idiot" or "moron."
