"I think Pervy Sage suits you better."
Jiraiya was rather unhappy with Boruto's assessment. After all, he was the author of Icha Icha Paradise, one of Konoha's Sannin, and a master of toad summoning-practically Mount Myōboku's spokesman.
With credentials like those, he commanded respect wherever he went. Yet today, some blond brat had the nerve to mouth off right to his face and call him Pervy Sage.
Worst of all, the son of his own student, Minato, had joined in with the brat. That made it rather hard for him to save face.
It seemed he would have to show some real skill to impress these two little brats.
"Damn it, you little brats! I'm seriously strong, you know! Let me show you an amazing technique. An S-Rank one!"
Jiraiya smugly held out his right hand and began gathering chakra.

"This technique is called the Rasengan."
Before long, a Rasengan the size of a bowl had appeared.
Naruto exclaimed, "Wow! That's huge! What an awesome Rasengan!"
The moment Naruto saw the Rasengan, he felt that this ninjutsu suited him perfectly. As though something in his DNA had been awakened, he stared at it, spellbound.
Boruto, however, gave a dismissive snort.
"Pfft. That's it?"
As he spoke, a matching, slightly translucent Rasengan appeared in Boruto's hand.
The sight nearly made Jiraiya's jaw hit the ground.
"I-I-I... Wh-what... How do you know the Rasengan?"
"Huh? Is it supposed to be hard?"
Boruto's offhand remark was pure showing off. The difficulties and hardships he had faced when first learning the Rasengan were still vivid in his
