Oder "Was zum Teufel...?"

i would say "domasla" was more correct, although i can only speculate and due to the fact i have only really spent time in the north of Germany (Berlin) but whenever i came across this, it was "was zum Teufel" so maybe it's a regional thing but i would say this is the closest example from the above. Hope this helps :)

Was zur Hölle?

Oder auch : "Was zum Henker?"

thank you, inblank:)
