Honestly I'm surprised that Boruto even learned the Rasengan from Konohamaru.
*Boruto is complaining that the Rasengan is too hard, and Konohamaru finally gets him to realize how important this technique is due to it being created by his Grandfather"
Konohamaru: "Watch me carefully, then you do it like eh"
Notice how Konohamaru, unlike Jiraiya, doesn't explain how you are actually supposed to break the ball with linguistics. Instead he's just showing Boruto examples of him popping the balloon without actually showing him how it works. It's basically like teaching someone how to drive, but instead of actually showing them, you just drive around :lol
Boruto: "I know! I know!"
Boruto: "But it's not working at all like "eh'
Konohamaru: "Don't talk like me!"
Boruto: No "eh" means "this"
Boruto: "eh" means this in my hand
Konohamaru: Quit saying: "eh, eh, eh"
Boruto: Speak for yourself!
Notice how Boruto is trying to tell Konohamaru that "eh" is the thing he has been saying from the start of the Rasengan training, and dumb ass Konohamaru is acting as if Boruto is mocking his way of speaking because he keeps repeating what Konohamaru is trying to explain!
LOST MY RESPECT. Stick to running away from pandas.
