flash in the pan
Meaning
A sudden success or excitement that lasts only a short time and is soon forgotten.
Origin
Originally referred to an early firearm’s priming pan: the powder might flare (“flash”) without igniting the main charge, producing a brief burst with no result. It came to mean something that looks promising but quickly amounts to nothing.
Notes
Often mildly negative: suggests something seemed exciting or successful but didn’t last or deliver. Used for people, trends, products, or events.
