I know this is probably just unimportant but i am just bored

In many episodes we get to see Sakura's alter ego (Inner Sakura) shouting SHYAAN NAROU! I caught TW's sub on those episodes and its always translated as "Hell yeah". Somehow I just dont think its that cheesy...

What's ANBU/Aone translation or if anyone has a better meaning for that? Incidentally its also the title for Episode 42.
