A DELIGHTFUL FRENCH IDIOM.

It came up in a French news story: “Un quart d’heure de gloire warholien” (“A Warholian fifteen minutes of fame”). It seems perfect for dropping into casual conversation: “He will enjoy his quart d’heure de gloire warholien, and then we shall have done with him.” This will baffle your acquaintances and make them think of you as a pompous twit, which will spare you the necessity of any further conversation with them.

The phrase is also often translated “quart d’heure de célébrité,” as in “‘À l’avenir chacun connaîtra son quart d’heure de célébrité’ prévenait Andy Warhol en 1968” (from the France culture site).
