Drunk angered, raise your weapon (2,5)
I believe the answer is:
en garde
'raise your weapon' is the definition.
(warning to a fencer to prepare for attack)
'drunk angered' is the wordplay.
'drunk' is an anagram indicator.
'angered' is an anagram of 'EN GARDE'.
(Other definitions for en garde that I've seen before include "Prepare to fence!" , "French opening position in fencing - protect yourself" , "warning of attack" , "Warning cry in fencing" , "(In fencing) in a defensive stance" .)
