Head supporter (4)
I believe the answer is:
neck
I believe this is a double definition.
'head' is the first definition.
(thesaurus)
'supporter' is the second definition.
(thesaurus)
(Other definitions for neck that I've seen before include "Body part associated with impudence" , "Body part and the nerve to do something" , "One may get it in it!" , "Pet" , "Isthmus - audacity" .)
