Playful crime fools jerks (10)
I believe the answer is:
frolicsome
'playful' is the definition.
(similar in meaning)
'crime fools jerks' is the wordplay.
'jerks' is an anagram indicator (I've seen 'jerk' mean this).
'crime'+'fools'='crimefools'
'crimefools' anagrammed gives 'FROLICSOME'.
(Other definitions for frolicsome that I've seen before include "Lively, playful" , "Enjoying a prank" .)
