Can anyone think of any other euphemisms for "What the heck?"?

Question

I mean, like "What in the wide, wide world of sports is goin on around here?"

Answer 1

F----It

Answer 2

What the P***k

Answer 3

"What the heck" is itself a euphemism for What the h-e-l-l.

You could say, in regular civilized English: what in the world is that ? or what in the world does it mean?

Nothing wrong with speaking properly.

Answer 4

Soleil is quite correct.  A common substitution for what the heck is, "What in Blazes?" which is also a reference to the down below.

Answer 5

What the @uck.

Who the h**l cares.
