Toad"eat`er (?), n. [Said to be so called in
allusion to an old alleged practice among mountebanks' boys of eating toads
(popularly supposed to be poisonous), in order that their masters might
have an opportunity of pretending to effect a cure. The French equivalent
expression is un avaleur de couleuvres. Cf. Toady.] A
fawning, obsequious parasite; a mean sycophant; a flatterer; a toady.
V. Knox.
You had nearly imposed upon me, but you have lost your
labor. You're too zealous a toadeater, and betray
yourself.
Dickens.
