Bloody wound, my dear chap! (3,3)
I believe the answer is:
old boy
'my dear chap' is the definition.
I can't tell whether this definition defines the answer.
'bloody wound' is the wordplay.
'wound' indicates anagramming the letters (wound can mean twisted or turned around).
'bloody' is an anagram of 'OLD BOY'.
Can you help me to learn more?
(Other definitions for old boy that I've seen before include "Former member of a school" , "Alumnus (with network)" , "Male ex-pupil" , "my dear chap!" , "Mate" .)
