Eccentric hugs that hurt wimp (6)
I believe the answer is:
coward
'wimp' is the definition.
(I've seen this before)
'eccentric hugs that hurt' is the wordplay.
'eccentric' becomes 'card' (I've seen this before).
'hugs' means one lot of letters goes inside another.
'that hurt' becomes 'ow' (exclamation of pain).
'card' placed around 'ow' is 'COWARD'.
(Other definitions for coward that I've seen before include "whose encounter was briefly filmed" , "Person without courage" , "Gutless type" , "Person who is excessively fearful, lacks courage" , "Chicken" .)
