Hotchpotch makes fag roar (7)
I believe the answer is:
farrago
'hotchpotch' is the definition.
(synonyms)
'makes fag roar' is the wordplay.
'makes' indicates anagramming the letters.
'fag'+'roar'='fagroar'
'fagroar' is an anagram of 'FARRAGO'.
(Other definitions for farrago that I've seen before include "Mix" , "Confused mixture" , "mess!" , "Motley assortment - Afro rag (anag)" , "A motley hotchpotch of things" .)
