An event that would surely cause the mass death of thousands of people is surging in popularity on Facebook.

The event, called Pop a Manu off the Harbour Bridge for Harambe, brings New Zealand's love of water, iconic infrastructure, wildlife and memes to the fore, and has seen more than 6000 people express interest in attending.

However, popping manus - a popular Kiwi slang term meaning doing bombs into water - off Auckland's 43.27m-high bridge would likely not end too well, with death or at least serious injury likely when falling into water from such a height.

Details of what the event entails remain hazy, with its description on Facebook simply stating "Hearty bombs off the bridge for the cuzzie, Harambe! Chur Bada (sic)."

Harambe was a silverback gorilla shot and killed at a US zoo in June, when a boy snuck into its enclosure and was dragged around by the animal. The gorilla's death has belatedly sparked a popular internet meme.

The event is scheduled to take place on September 11, though it almost certainly won't actually happen - at least, that's our hope.
