One minute you're flavour of the month, top of the bestseller charts, and the next minute you're forgotten. Filmstars seem to be interested in whatever cause is the latest flavour of the month. Note: People sometimes mention other periods of time such as year, week, or moment instead of month. Monetarism was the flavour of the year. Suddenly, he was flavour of the moment on both sides of the Atlantic. Note: These expressions are often used to suggest that the popularity of someone or something is unlikely to last long.
