"Gunnerstrophe?"
This word is not even a good paronomasia.
Words that end in "strophe" usually follows a strict format.
Some words that I could think of:
anastrophe
antistrophe
apostrophe
catastrophe
epistrophe
...
and of course strophe itself is a word.
The format is basically [....][i, o, a] which means the letter before 'strophe' has to be one of the three.
Up till now OOO followed this rule and did quite a good job:
Caketastrophe
kataclysmic/katastrophe
In fact 'gunnerstrophe' isn't even pronounceable, "Gunner-strophe?" If read quickly it will become "gunnastrophe", something like that.
Same words that has some kind of strict format inclue those 'phile' words, such as "pedophile, necrophile, formicophile, chronophile, sinophile, anglophile, japanophile etc".
