A word often said by Naruto (from the anime/manga Naruto) at the end of his sentences, it has no actual meaning. It's much like Kenshin's (of Rurouni Kenshin)'De-gozaru-yo'.
Many people are baffled over the fact that Naruto almost always says 'Dattebayo' at the end of his sentences.

dattebayo the word that naruto often ends his sentances with. verbaly, it is said as "-ttebayo"
dattebayo has no real meaning, and the closest english equivelent is a pirates "arrgh!"
in the english dub (which is constantly plauged by crazed otaku, despite it being an excelent dub and true to the original)it is translated as "belive it!" in order for the mouth flaps to fit.
The specific "dattebayo" is not well known to even much of the Japanese native population.
The "dattebayo" specific ending can be considered a colloquial verb ending that makes the speaker sound uncultured, brusque, and trying to seem tougher than they really are.
I'm gonna be the next hokage, dattebayo!

on a side note despite the english dub version.

dattebayo does not mean belive it.

dattebayo has no realy meaning other than its a kinda of phrase that children add to the end of their sentances.

the english dub generealy translates dattebayo as belive it:

1. because otherwise narutos mouth would be moving and there would be no sound
(they do not reanimate for engdubs just put in different words)
2. its what the creaters of the engdub version of naruto best reflected the childish connotations of dattebayo

if you watch the japanese and engdubs at the same time there are alot of times in the japenese where naruto says dattebayo or -tebayo and there is no reference to it in the eng dub

The word dattebayo is used by the manga and anime character Uzumaki Naruto. It is a word created and used by Naruto and the end of sentences. Though the meaning is different, it is much like Canadians saying "eh" or Jay of the Jay and Silent Bob duo saying "Snoochie Boochie" or "Snoogans".
That's my way of the ninja, dattebayo!

naruto uses very often the word dattebayo in his speech. the most of the time wants to emfasizing that he just said. its like "what I'm saying is" or "is what am I saying". naruto lived alone, outside of the society of konoha for so many time.but he wanted so much to be a part of society. he was searching someone to recognize him. he wants so much someone to listen what he's says and what he thinks. its in his nature to flaunt what his says and does.so its like to stand up and speak and saying "dattebayo:is what am i saying" to show "this is my strong opinion and i have to say it", " and everybody listen to me, including myself" fearing that there is nobody not hearing him or not understanding him.. dattebayo is the courage of the opinion of naruto that stucks in his mind and at the end of his sentence..

Depending on how it's used it can also mean "I am what they have made me"
"I won't give up just because of a little pain, dattebayo"

dattebayo means nothing, it is only sounds that infants make when then cant form words, like when a baby says goo-goo ga-ga. They are parts of speech but don't mean anything.
