It means "water-drinker" and since I am trying to be more of an aquabib it seemed both useful and a propos.
Aquabib also has a great example sentence: "aqua-bib by day, alcoholic by night - that's your grandfather." Oh, snap!
Feel free to send me any words you discover that mean "naturally gifted in Pilates," "blessed with hair that is perfectly coiffed without styling," "completely immune to the Siren-song of popular television shows like 'Glee'," or "rises, fully rested, with the dawn" so that I can get to work on those aspirations as well . . .
