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. Naruto inherited this from his mother, Kushina Uzumaki, who would end her sentences with when she got excited or angry, something she hoped that her son would not inherit, which did not came true.

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 lip movements from the original Japanese release. Around the start of the Chūnin Exam arc, however, "Believe it" fell out of use. It also is translated as "Do you get what I'm saying?".

He also uses the phrase before the fight with Zabuza where it was hard to match the lip movements.
