The Great Tribble Hunt
From Memory Alpha, the free Star Trek reference
The Great Tribble Hunt was the nickname that Odo gave to the extermination of the tribble species by the Klingon Empire in the late 23rd century, due to the Klingons deciding that tribbles were an ecological menace.
When told of the event by Worf aboard Deep Space K-7 in 2268, Odo asked him "Do they still sing songs about The Great Tribble Hunt?" (DS9: "Trials and Tribble-ations")
