Dattebayo and Believe It

In the original Japanese release of Naruto, 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, however, "Believe It!" was 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 also used to match the mouth flaps from the original Japanese release. Around the start of the Chunin Exam arc, "Believe it" fell out of use. It also is translated as "Do you get what I'm saying?"

Some rough translations have said that sentences like "Nan dattebayo?" means "What the heck?" is quite close to "Nan da yo" meaning "What the hell," while "Wakkattebayo" means "I get it," "Got it," or "I get it already." The suffix "-ttebayo" is added to verbs, which makes them function the same as if he were saying "dattebayo."
