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 is used to match the mouth flaps from the original Japanese release. Roughly near the beginning of the Chunin Exam arc, "Believe it" fell out of use. It also is worded as Do you get what I'm saying? In Spanish, it was translated as De veras!, meaning "Really!"
