An exclaimation of when something is ironically disturbing, but not distressing.
In every scary movie, to let you know when something scary is about to happen, they play scary music -- usually in short staccato burts which repeat and build something to the effect of: dun-dun, dun-dun dun-dun-DUN-dun.

well, a friend and I adapted that cadence and evolved it to: stunna, stunna-bunna-bunna when adding the sing-song phrasing, but when speaking in conversation, referred to things ironcallly scary as simply "Stunna McBunna"
