Drunk prepared to be fired (6)
I believe the answer is:
loaded
'drunk' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for loaded that I've seen before include "Magazine" , "Burdened - with lots of money" , "tight" , "Burdened; rich (slang)" , "Laden; rich" .)
