Martial art nuts donate wok (3,4,2)
I believe the answer is:
tae kwon do
'martial art' is the definition.
(tae kwon do is a kind of martial art)
'nuts donate wok' is the wordplay.
'nuts' is an anagram indicator (nuts can mean crazy).
'donate'+'wok'='donatewok'
'donatewok' with letters rearranged gives 'TAE KWON DO'.
(Other definitions for tae kwon do that I've seen before include "Martial art Olympic event since 2000" , "sport" , "Martial activity" , "Koreans fighting" , "Martial art display" .)
