Fighter's moves do not wake bats (3,4,2)
I believe the answer is:
tae kwon do
'fighter's moves do not wake bats' is the definition.
I can't judge whether this definition defines the answer.
'do not wake bats' is the wordplay.
'bats' indicates an anagram (slang for mad).
'do'+'not'+'wake'='donotwake'
'donotwake' anagrammed gives 'TAE KWON DO'.
Can you help me to learn more?
(Other definitions for tae kwon do that I've seen before include "combat" , "Martial art display" , "sport" , "Martial art Olympic event since 2000" , "Martial activity" .)
