Ok. I have seen alot of theories on the net of what Naruto says at the end of nearly every sentence, Dattebayo!
I hear alot of other characters in Naruto and other animes finish the sentance with Bayo or xxxxxbayo and it would seem that the general feeling is that this is an exclamation type word with no meaning but to give accent to the sentance.

Can anyone here clear up this strange saying dattebayo!
