Making a buzzing or humming sound; vibrating audibly.
From Latin 'bombinare,' derived from 'bombus' (a buzzing sound). The present participle '-ing' form indicates ongoing action.
Thomas Pynchon used 'bombinating' in his novel 'The Crying of Lot 49'—it's the kind of rare, wonderfully specific word that appeals to writers because it sounds exactly like what it describes!
