@Jizo, it's actually more for Kamui than against. Naruto didn't recognize Sasuke's Space-Time Ninjutsu now, which means that he (most likely) doesn't name them in reference to the action. xD

From the looks of things, Naruto is not fancy referencing to techniques with actual names. And since the function is exactly the same, It would be safe to say that, for the time being, it's Kamui.
