Dishevelled drunk emptying pockets (7)
I believe the answer is:
unkempt
'dishevelled' is the definition.
(I've seen this before)
'drunk emptying pockets' is the wordplay.
'pockets' indicates the answer is hidden within the clue (pocket can mean to contain).
'UNKEMPT' is hidden in the letters of 'drunk emptying'.
(Other definitions for unkempt that I've seen before include "Tousled and untidy" , "shabby" , "Not neatly combed" , "(Of hair) needing a comb?" , "Looking untidy or neglected" .)
