"Oi, Sasuke-teme!"
"What do you want, dobe?"
"I'm not a dobe, you...you... teme!"
"Your vocabulary impresses me, usuratonkachi."
"I hate you."
"I hate you too, Naruto."
Naruto isn't quite sure how long this banter has been going on, but it's become such a routine that it seems his day isn't complete without it. They don't mean the words anymore- they've long since lost any hatred for each other, and that hatred has been replaced with a warm, fluttery sort of feeling that even Sasuke with his expansive vocabulary can't name.
