Awkward when dancing I'm shafted (3-6)
I believe the answer is:
ham-fisted
'awkward' is the definition.
(I've seen this before)
'dancing i'm shafted' is the wordplay.
'dancing' is an anagram indicator.
'im'+'shafted'='imshafted'
'imshafted' with letters rearranged gives 'HAM-FISTED'.
'when' is the link.
(Other definitions for ham-fisted that I've seen before include "Clumsy, awkward" , "I'm shafted, being clumsy" , "Lacking 5 across" .)
