So this answer explains why Naruto say "dattebayo" or "believe it" in the English translations, being that he inherited it from his mother.
In earlier episodes of Naruto when Sakura goes to think of what she really wants to say, this occurs in the form of white drawing lines of Sakura with writing on her forehead with black background. See the image below:
In the English dub, the second Sakura often ends her sentences by saying "cha".
What is the reason for this? Is this something she picked up from her parents like how Naruto inherited his mother's habit, or is there some other explanation for this?
