siren slide

A rapid interest in something followed by an immediate loss of interest; a short lived trend.

Metaphorically, like the Doppler Effect: sirens coming closer and getting louder, and then decreasing just as quickly.

Guy 1: What ever happened to the guy that did that song Gangnam Style?

Guy 2: American interest in a Korean pop star? Total siren slide...
