Crease my carpet had (9)

I believe the answer is:

corrugate

'crease' is the definition.
(thesaurus)

'my carpet had' is the wordplay.
'my' becomes 'cor' (both are expressions of surprise).
'carpet' becomes 'rug' (synonyms).
'had' becomes 'ate' (e.g. I had an ice cream).
'cor'+'rug'+'ate'='CORRUGATE'

I've seen this clue in The Independent.
