Revolting part, I'm hollow (6)
I believe the answer is:
armpit
'hollow' is the definition.
(thesaurus)
'revolting part i'm' is the wordplay.
'revolting' is an anagram indicator.
'part'+'im'='partim'
'partim' with letters rearranged gives 'ARMPIT'.
(Other definitions for armpit that I've seen before include "part of the body" , "evident given "hands up"!" , "Where to put a crutch" , "depression which is personal" , "Hollow between limb and shoulder" .)
