Crude thug with money (5-3-5)
I believe the answer is:
rough-and-ready
'crude' is the definition.
(I've seen this before)
'thug with money' is the wordplay.
'thug' becomes 'rough' (both can mean a violent person).
'with' becomes 'and'.
'money' becomes 'ready' (ready can informally mean cash).
'rough'+'and'+'ready'='ROUGH-AND-READY'
(Other definitions for rough-and-ready that I've seen before include "Crude but effective" , "Hastily prepared, but adequate" , "Crude - unpolished" , "Serving well enough for the task" , "Unrefined" .)
