Damn, I don’t think “fluffer” counts as a word.
Well, back to the drawing ballsack.
OK, replace my earlier entry with “relativistic spatulas”.
Score: 212,000 x 30,200 = 6.4 billion
(I’m clearly ignoring the suggested words, as I’m having a hard enough time without constraints.)
FINALLY…
crabapple polyp
40900 * 62900 = 2,572,610,000

uproar
freaky morphometric
664000 x 25100 = 16,666,400,000

First zut beats me while I am previewing. Then ChordedZither does the same.
And all the time I still can’t beat a billion, let alone 16.6 billion - great job Zither…
Aw, shoot CaveMike. Post yours anyway. It’s a friendly game.
kinetic + zithern

Next word: polyovarian.
Scratch that. Polyovarian returns one hit on google anyway.

the + polyovarian gives me a quick 2.48 billion
try: bacchanal
