Like a wet noodle (4)
I believe the answer is:
limp
'like a wet noodle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for limp that I've seen before include "Walk with difficulty" , "Walk with an uneven stop" , "Lacking stiffness" , "Walk badly; not stiff" , "Walk haltingly" .)
