"Naruto, where are you going?" Sakura asked. Naruto stopped in mid-step and looked back at her. They were waiting for Kakashi-Sensei and Naruto was trying to sneak off somewhere.
"I'm going to go and get some...Ramen. Yea, ramen." Naruto said quickly, already turning and trying to run off. Sakura quickly jumped in front of him, cutting him off.
"Nice try, Naruto. Now, where are you really going?"
"Umm, To fuck your mom? What does it matter?"
"Shut up or I'll kick your you so hard; your dick will turn into a vagina!" Sakura screamed.
And this is the real reason Naruto became Naruko.
