pantagruelist

I don't know the context (if any) that drove the search; but in any case it is used allusively (take note, wwftd master!), pertaining to, characteristic of, or appropriate to, Pantagruel, represented by Rabelais as a coarse and extravagant humorist, dealing satirically with serious subjects.

"Had I mixed more with the world than I have, I should probably have become a Pantagruelist."
- James Russell Lowell (1847)

Next week, the battle that makes Godzilla vs Mothra look like patty-cake. Pantagruel meets Gargantua in the mother of all cage matches. The last one to die is the winner.
