chapfallen or chopfallen (CHAP-faw-luhn, chop-) adjectiveNice usage there, even if JBJ would be more fittingly described as "crapfallen." "Chapfallen" sounds more appropriate as an assessment of drunkenness to me, though. Either way, dulce et decorum est....
Dejected or dispirited. [From chap or chop (jaw) + fallen.]
"Jon Bon Jovi, the New Jersey rock 'n' roller, says he's chapfallen and desolate over rumors that his band is about to break up." Chris Reidy; Bon Jovi's Funk; Boston Globe; Aug 7, 1990.
(And "clapfallen?" That's reserved for Tommy Lee.)
