Wasn’t horrible around relatives (8-2-3)

I believe the answer is:

brothers-in-law

'relatives' is the definition.
(brother-in-law is a kind of relative)

'wasn't horrible around' is the wordplay.
'around' is an anagram indicator.
'wasnt'+'horrible'='wasnthorrible'
'wasnthorrible' with letters rearranged gives 'BROTHERS-IN-LAW'.

(Another definition for brothers-in-law that I've seen is " Relations by marriage".)

I've seen this clue in The Times.
