Sakura, Kushina are known to have their own version of what Naruto says.........If you haven't realized something like this since the pain arc....then you my friend are here to troll.
It's a made up Naruto word roughly meaning "Ya Know". But, since you're most likely trolling, then you don't care what I say and will have another excuse to "What does it mean? Why does no one else say it?"
For the record, I'm actually not trolling. Thanks for actually answering my question, and not just saying that I was trolling like literally everybody in this thread has been doing.
It's Dattebayo, and it can be translated as "Believe it", "You know" and "Know what I mean". It's Naruto's trait, just like Kushina was using Dattebane when she was excited, angry etc. Naruto succeeded this from his mother and that's why he's the only one using the replica.
