Deck's wet -- I crumpled -- most shameful (9)

I believe the answer is:

wickedest

'most shameful' is the definition.

'deck's wet i crumpled' is the wordplay.
'crumpled' indicates an anagram.
'decks'+'wet'+'i'='decksweti'
'decksweti' anagrammed gives 'WICKEDEST'.

(Another definition for wickedest that I've seen is " Most wonderful".)

I've seen this clue in The Telegraph.
