Hotchpotch making fag roar (7)
I believe the answer is:
farrago
'hotchpotch' is the definition.
(synonyms)
'making fag roar' is the wordplay.
'making' indicates anagramming the letters.
'fag'+'roar'='fagroar'
'fagroar' is an anagram of 'FARRAGO'.
(Other definitions for farrago that I've seen before include "Confusion" , "Motley assortment of things" , "Mish-mash" , "Confused mixture" , "A hotchpotch, perhaps of nonsense" .)
