Looh Inuyasha's taunting her. He addressed her as 'Kikyou-sama'- lady Kikyou. In short, it can be 'mighty Kikyou'.  But hey, wouldn't you feel rather sour to someone who pinned you 50 years to a tree? Life just stops, right there. Kikyou died afterwards, yet Inuyasha was sealed. In suspended animation Inuyasha slept upon that tree. Fifty years of war passed by, and he slept through. Back to the Souplet!
