I think it's "vay ha" but the person speaks it using southern accent. so it sounds dzay ha It means "really?"

mmmm... lol thanks for the answer :D. to clarify, in the context that it was used (from what i understood -_- haha) that was all that was said... so i don't think "oh really?" would make much sense...? idk... haha it's just driving me CRAZY >_<;; maybe it was like... eeha? eehow? i know the 'e' sound was kind of dragged out...? if that even makes a difference... -0-;; haha anyways thanks for trying :D

What you're probably hearing is "vay ha," but depending on the region that the person is from, it can sound like a "y" in the beginning. Vay ha means 'oh really?'
