Awkward person playing charades (4,4)
'awkward person' is the definition.
(term for a stubborn or tough person)
'playing charades' is the wordplay.
'playing' is an anagram indicator.
'charades' with letters rearranged gives 'HARD CASE'.
(Other definitions for hard case that I've seen before include "Intractable person", "challenge to legal team?", "Tough guy", "Brief problem, perhaps", "Tough person to deal with".)
