Somewhere in my past the chorus to the theme (by Queen) from the 1980 Flash Gordon movie got quasi-embedded in my brain--particularly that couplet:
Flash! A-ah!Savior of the universe!
Over time my brain changed the second line to "Defender of the universe" (which I think works better in the meter, but that's another topic) but the melody remained, and the key (of course) was the "A-ah!" vocalization after the hero's name. It's not as though I was a huge fan of the movie (I was not) nor a huge fan of the song (it's fine); but that part was just an earworm that was in me permanently.
For no good reason other than my own amusement, occasionally I'd adapt it and substitute another single-syllable word where the "Flash!" was, to elevate the term in a ridiculous way; e.g., "Cheese! A-ah! Defender of the universe!"--although I have no recollection of using that one in particular. It's always spontaneous, tossed out in the moment when an appropriate word comes up in our conversations, as a jocular interjection, so they never stick with me.
