Ha! It's "criminently" or "criminitly," an expression of surprise or astonishment. Derives from older British English "criminy.""Crime in Italy?" which is a shortened version of "There's crime in Italy?".
My father used to say this when someone said something patently obvious to him... like he didn't already know - or everybody should know by then.
I have no doubt he picked this up after returning from WW II and working for some families in Des Moines in the late 40's and early 50's.

Etymology of Criminently
English word criminently comes from English criminy (A minced oath that expresses surprise.)

But I can understand someone mishearing it, especially as a kid. Kinda like "we're going to see da rabbits (Cedar Rapids)."
