Sneak unused to follow society (5)
I believe the answer is:
sidle
'sneak' is the definition.
(thesaurus)
'unused to follow society' is the wordplay.
'unused' becomes 'idle' ('idle' can be a synonym of 'unused').
'to follow' is a charade indicator (letters next to each other).
'society' becomes 's' (common abbreviation in names of organisations).
'idle' after 's' is 'SIDLE'.
(Other definitions for sidle that I've seen before include "Make cautious progress" , "Edge along furtively" , "Walk obliquely" , "Move in furtive manner, edge along" , "Walk sideways like crab" .)
