Pickled, like worms, say? (7)
I believe the answer is:
legless
I believe this clue is a double definition.
'pickled' is the first definition.
(both can mean drunk)
'like worms say?' is the second definition.
(worms don't have legs)
(Other definitions for legless that I've seen before include "Sozzled - lacking limbs" , "Missing a pin" , "Drunk (as a worm?)" , "Extremely drunk, lacking lower limbs" , "As one may be after convivial time in club" .)
