Nick, trendy gangster and outlaw (5,4)
I believe the answer is:
robin hood
'outlaw' is the definition.
(Robin Hood is an example)
'nick trendy gangster' is the wordplay.
'nick' becomes 'rob' (both can mean to steal).
'trendy' becomes 'in' ('in' can mean fashionable).
'gangster' becomes 'hood' (I've seen this before).
'rob'+'in'+'hood'='ROBIN HOOD'
'and' acts as a link.
(Other definitions for robin hood that I've seen before include "Sherwood outlaw" , "Lawbreaker" , "English folk hero" , "Pantomime character" , "Old thief" .)
