I couldn't find bumph at M-W.com. If it's deemed ineligible, I offer:
plumb
Bumph is listed. Check it out, pretty funny etymology...
Please continue from BUMPH.
jtf, want to rethink that? Peplum doesn't follow plumb or bumph.
Given the meaning, it doesn't seem like there should be a plural, but m-w accepts it (and I can't think of anything else), so...
bumphs
Jtf must be having an attack of dyslexia
There is at least one word that can follow PRANCED.
