suckth

v. Of the root "suck." (1) Early modern English verb implying the action of suction: e.g., "The vacuum suckth." Except there weren't any vaccums in 17th century England. Which I suppose may pose a problem for future lexicographers.

(2) A term of derision uttered by an individual with a lisp: e.g., "Thith movie suckth!"
