Arch Stanton and Paula Schultz

Three obscure words for your face:

• mammothrept — meaning "a spoiled child," its etymological roots go back to the Greek for "a child raised by one's grandmother"
• logodaedaly — meaning "clever in the use of words," it's the Greek word part for "word" (as in "dialogue" and such) plus a permutation of the Greek mythological character Daedalus, who designed the Labyrinth and other ingenious things
• jumentous — meaning "resembling horse urine," and simultaneously useless and wonderful because of that
