Your made up horse name made me just think of (which may already exist outside my awareness) a corollary to Poe's Law.

"That without a clear indicator of the author's intent, it is impossible to create a parody of race horse names so obviously exaggerated that it cannot be mistaken by some readers for a sincere and accurate name of a horse."

We could call it the "Derby Law".

I actually searched for "Fancy Dancy Magic Prancy" because I thought that might be an actual horse. I found out it's a reference to PBF, but nonetheless it /could/ have been a real horse.
