n. Used in a derogatory way to describe a dramatization that is contrived and unconvincing (as in 'so much Sardoodledom').
Don't believe me? Ask this kid...
Like a lot of nasty spelling bee words, this one derives from a person's name, making it impossible to deduce from even the most extensive knowledge of Greek and Latin roots. (In case you're wondering, it is named after a rather creepy-looking 19th century French dramatist by the name of Victorien Sardou.)
And for the same reason, you are unlikely to see this word sprawled across the Scrabble board - no proper nouns, remember?! So you can quit dreaming about the applause following your miraculous counter-play to your opponent's DOODLE opener ;-)
