Hangdog. As in Hangdog Hotel Room. At first I thought Gordon might have made the word up, but knowing his command of the english language I thought better and looked it up.
Harper-Collins Essential English Dictionary describes hangdog (adj.) as dejected, ahamed, or guilty in appearance in manner. Webster's describes as (adj.) showing a sense of guilt, a guilty look; (noun) a sneak, a degraded person; (adverb) low, sneaking, ashamed. Regardless of how used, I'd never heard of the word before!
RM--like you, I'd never heard of flotsam either, but you beat me to it
