Crazily cages as top whipping boys (10)
I believe the answer is:
scapegoats
'whipping boys' is the definition.
('scapegoat' can be a synonym of 'whipping boy')
'crazily cages as top' is the wordplay.
'crazily' indicates an anagram.
'cages'+'as'+'top'='cagesastop'
'cagesastop' is an anagram of 'SCAPEGOATS'.
(Other definitions for scapegoats that I've seen before include "Victims" , "they could be held responsible" .)
