Met punk perhaps looking rough (7)
I believe the answer is:
unkempt
'looking rough' is the definition.
'unkempt' can be an answer for 'rough' (I've seen this before). I'm unsure of the 'looking' bit.
'met punk perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'met'+'punk'='metpunk'
'metpunk' is an anagram of 'UNKEMPT'.
Can you help me to learn more?
(Other definitions for unkempt that I've seen before include "in a mess" , "Met punk looking neglected with matted hair" , "Tousled and untidy" , "Slovenly" , "Badly turned out" .)
