Four repeatedly out rustling (4-4)

I believe the answer is:

frou-frou

'rustling' is the definition.
(I've seen this before)

'four repeatedly out' is the wordplay.
'four repeatedly' can mean two replacements for 'four'.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'four'+'four'='fourfour'
'fourfour' anagrammed gives 'FROU-FROU'.

I've seen this clue in The Globe and Mail.
