ok this might be a good one my last name is Fiutek what do you have to make of that.
The word fiut and derivatives predate the current slang usage. Mainly fiut was an interjection implying something lightning swift like the Polish word myk or the English zip or whiz. hence the verb "fiutnąć" (to pinch,swipe). Fiut was also the name of a small silvery fish, the bleak, aka uklejka in Polish.
So there's no reason to be ashamed of the name Fiut or Fiutek. I recently ran across somone ashamed to admit his grandfather had been surnamed Dupla (he confused it with dupa), whereas this is nothing more than the Ukrainian word for tree hollow (Polish dziupla).
