Stupid jeer ruined witticism (3,7)

I believe the answer is:

jeu d'esprit

'witticism' is the definition.
(jeu d'esprit is a kind of witticism)

'stupid jeer ruined' is the wordplay.
'ruined' is an anagram indicator.
'stupid'+'jeer'='stupidjeer'
'stupidjeer' is an anagram of 'JEU DESPRIT'.

(Another definition for jeu d'esprit that I've seen is " Light-hearted display of wit".)

I've seen this clue in The Times.
