A New York minute is an instant. Or as Johnny Carson once said, it's the interval between a Manhattan traffic light turning green and the guy behind you honking his horn.

It appears to have originated in Texas around 1967. It is a reference to the frenzied and hectic pace of New Yorkers' lives. A New Yorker does in an instant what a Texan would take a minute to do.

An imaginary measurement of time that indicates an extreme quickness. Lending itself to the fast-paced lifestyle associated with New York City.
When I was in the Bronx I got mugged, shot, raped, and murdered in a New York Minute. In Detroit it would take at least 2.

A very fast minute. You use this saying when you'll be back, or have something done, really quick.

Traditionally it has meant in the blink of an eye.

But after 9/11, due to the large air play of the song New York Minute (by Don Henley, and covered by the Eagles) it has taken on the further connotation of "A Blink Of an Eye that Changes Everything." Cataclysmic.
A sudden accident that takes a life. Any senseless violence, or of course the 9/11 attacks themselves. But it can be a good event too. When New York legalized Gay Marriage, the media reported the event as a New York Minute - the signing of that bill would change the state forever.
