What it means
It means the person, thing, or trend everyone can't shut up about right now, with the built-in eye roll that the fuss probably won't last. You'd use it at work, in the pub, or anywhere people are side-eyeing hype and waiting for the next shiny obsession to steal the spotlight.
Usage examples
"He’s the flavour of the month at work after fixing the printer. Struts round like IT royalty. Give it a week and Sharon’ll be hyping someone else."
"That new app is the flavour of the month, everyone is suddenly raving about it."
"He is the flavour of the month with the boss right now, but we will see how long that lasts."
"That band's the flavour of the month on TikTok right now. Give it ten minutes and the internet'll crown a new darling."
"She's the flavour of the month with management since that big pitch landed, but office hype's got the lifespan of a cheap battery."
Where it comes from
It comes from American advertising, especially ice cream and similar products, where shops pushed a special flavour each month to keep people interested. By the mid 1900s it had jumped into everyday English for whoever or whatever's suddenly getting loads of attention, usually with a built-in hint that the fuss won't stick around.
