Most vulgar broadcast coverage of the Oscars (8)
I believe the answer is:
coarsest
'most vulgar' is the definition.
(I've seen this before)
'broadcast coverage of the oscars' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'coverage of' suggests removing the centre (the letters on the edges cover the rest).
'the' with its centre taken out is 'te'.
'te'+'oscars'='teoscars'
'teoscars' is an anagram of 'COARSEST'.
(Other definitions for coarsest that I've seen before include "Most uncouth according to Socrates" , "most vulgar" , "Socrates in most unrefined form" , "Most rough" .)
