Video ref overturned in bad-tempered farce (8)
I believe the answer is:
travesty
'farce' is the definition.
(synonyms)
'video ref overturned in bad-tempered' is the wordplay.
'video ref' becomes 'var' (I can't justify this - if you can you should give a lot more credence to this answer).
'overturned' is a reversal indicator.
'in' is an insertion indicator.
'bad-tempered' becomes 'testy' (testy means bad-tempered or irritable).
'var' backwards is 'rav'.
'rav' placed inside 'testy' is 'TRAVESTY'.
Can you help me to learn more?
(Other definitions for travesty that I've seen before include "'Farce, parody (8)'" , "False or distorted representation of something" , "Terrible distortion of something." , "Absurd representation" , "Farcical version" .)
