flash in the pan
Definition: (noun phrase) Something (or someone) that starts out with promise, but goes nowhere
Example:
At the beginning of her career, many critics predicted that Madonna
would just be a flash in the pan, but she has proved
them wrong.
Quote:
"You have to understand, Frank Bruno would not have been champion if I had not been in prison. Oliver McCall would not have been champion if I had not been in prison… They'd be a flash in the pan and would have made some money and opened up a restaurant or bar somewhere where they live at."
Though it might sound like a cooking reference, flash in the pan refers to gunpowder that explodes in the pan of an old-fashioned flintlock rifle, but doesn’t set the charge, so the gun doesn’t shoot. American slang has a number of similar expressions related to unsuccessful weapons.
For example, in Standard English, blanks are gun cartridges without bullets used for shoot-outs in movies. In slang, for a man to shoot blanks can mean that he is unsuccessful in the bedroom, or simply unsuccessful in getting his wife pregnant. And in World War I, a dud was a bomb that didn’t explode. Now, a dud is now something that fails, like a bad date or Gigli (sorry, J Lo fans). Unlike a flash in the pan, a dud doesn't usually look like it’s going to be successful at first.
If you live in the US, and have a reasonable amount of curiosity, now
you are probably wondering how the popular candy Milk Duds got
its name. Was it a failure? Apparently so. According to the Hershey’s
website, they called them duds because they failed to
come out perfectly round. Perhaps not the best advertising strategy, but
people buy them anyway.
