Dozens abroad show disgust (5,3)

I believe the answer is:

gross out

'disgust' is the definition.
(thesaurus)

'dozens abroad' is the wordplay.
'dozens' becomes 'gross' (gross can mean the number 144, ie 12 squared).
'abroad' becomes 'out' (abroad can mean away or out).
'gross'+'out'='GROSS OUT'

'show' acts as a link.

I've seen this clue in The Guardian.
