Tired? Try not to PANDICULATE

What's the word I'm thinking of? Today, it's...

PANDICULATE [pan-DIK-yuh-LAYT] (verb)

To stretch and yawn simultaneously

"I'm troubled with pandiculation, An ailment dire and rooted deep 'Tis caused by undue hesitation In rising from the couch of sleep." --George W. E. Daniels, "Pandiculation", in The Medical Pickwick (1921) (TWITO, page 106)
