Squiffy contestants finally given ratings (7)
I believe the answer is:
screwed
'squiffy' is the definition.
(both can mean drunk)
'contestants finally given ratings' is the wordplay.
'finally' says to take the final letters.
'given ratings' becomes 'crewed' (rating can mean a sailor).
The last letter of 'contestants' is 's'.
's'+'crewed'='SCREWED'
(Other definitions for screwed that I've seen before include "in serious trouble" , "Spoiled" , "Swindled; twisted into place" , "Fastened - cheated - drunk" , "Tightened - fastened (together)" .)
