Dattebayo and Believe It

In the original Japanese release of Naruto, Dattebayo! (だってばよ) is Naruto Uzumaki's catch phrase. He uses it at the end of most of his sentences as a way of making his speech unique. Dattebayo has no literal English translation, but Believe It! is used in the English dub whenever Naruto is making a big statement to keep a similar tone in the English version of the series. It also is worded as Do you get what I'm saying? In Spanish, it was translated as De veras!, meaning "Really!"
