Real drunk, real drunk (7)
I believe the answer is:
literal
'real' is the definition.
(I know that real can be written as literal)
'drunk real drunk' is the wordplay.
'drunk' becomes 'lit' (slang term).
'drunk' indicates an anagram.
'real' is an anagram of 'eral'.
'lit'+'eral'='LITERAL'
(Other definitions for literal that I've seen before include "Lacking imagination; misprint" , "Using words in their most basic sense, exact" , "Actual" , "Ill rate (anag.)" , "Taking words in their most basic sense" .)
