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)
