The best I can offer for you is to try a google search and enter the phrase
Pompitous of love. There is far too much for me to list it all here, but my first hit was on target for two songs I remembered it from, first being of course
The Letter a 1950's song by a group called
The Medallions (I have the 45 if anyone cares, and even if they don't). The author of that song explained how he created the word puppetuse and it essentially morphed into pompitous (in fact until the google search I thought it was pompitous). Fast forward into the 1970's and The Steve Miller Band gave us
Enter Maurice (which I do not recall) and
The Joker which I used to try to sing all the time until I was ordered to stop
...okay, okay, I only attempted to sing it and failed miserably since I am not vocally adept
. In the Joker the first verse is as follows:
Some people call me the space cowboy, yeah
some people call me the gangster of love
some people call me Maurice (whew whew..or something like that)
Cause I speak of the pompitous of love.
That last line of course refers to words from his earlier song Enter Maurice.
In Enter Maurice the song begins:
My dearest darling come closer so Maurice can whisper sweet words of epismetology in your ear and speak to you of the pompitous of love.
All of this is very very strange and please don't ask me what the heck epismetology is because that was also in The Letter, by The Medallions and I can't get a definition on it either. Anyway it appears from what I can tell from my quick look-around that yes indeedy Pompitous of love was made up.
As for my late cat, I used to call him my Sweet Begonia, my little bouillabaisse...
Rest in peace my sweet little cat.
