Skiers hurt mouth (6)
I believe the answer is:
kisser
'mouth' is the definition.
(I've seen this in another clue)
'skiers hurt' is the wordplay.
'hurt' indicates an anagram.
'skiers' is an anagram of 'KISSER'.
(Other definitions for kisser that I've seen before include "Skiers (anag.)" , "Mouth (slang)" , "Casanova" , "Amorous type" , "Slangy face of osculatory origin" .)
