Hearkens back to Mencken's ombibulous....which he coined to mean "I drink everything" [type of alcoholic beverage, that is]. He used to say, "I'm an ombibulous drinker." [there's an old thread on this here if anyone wants to search it] So...

That coupled with ambi-, and bibere seem to indicate an attempt to quantify and diversify the practice of something...a two-fisted dentist!?

ambi-bib-entists...hmmm, entists...a two-fisted lover of Ents! A LOTR allusion! OR, a two-fisted drinker of Ent liqueur (distilled from their essence, not made by the tree-creatures)

'N mebbe you're right, AnnaS, mebbe the snow is getting to me! The weather kind, that is! A nice shot of Ent whiskey, anyone?

Next item on the menu...Gollumburgers...no,no,no...I like Gollum too much...Orcburgers more like it, I think!
