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 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?"

In the spanish dub, it was translated as "Vaya que sí", which can be translated as "well, it comes to yes". That translation left the fans outraged.

In the latin american spanish dub it is also translated to "creelo!"

In the swedish manga, Naruto often says "typ" and "liksom" wich doesn't really have an english translation but it's a little bit like "like, totally, you know!" or maybe like "kinda´"
