THIS is the video flagged as THE BIGGEST CLIFF JUMP ON YOUTUBE – and, as the jumper drops 100feet, hitting the water at 54 mph, few would disagree.

Filming potentially deadly cliff leaps had become a craze on YouTube and this one, at a watering hole in Box Canyon, Carlsbad, California, California, has become a major hit.

It takes a heart-stopping 2.4 seconds for the jumper to hit the water, making a gut-wrenchingly explosive sound.

He emerges victorious shouting “you owe me lunch sucker!” - which one fan has pointed out may well be the 'coolest celebration ever'!
