Someone who violently diarrhoeas and vomits at the same time, generally to the amusement and/or disgust of a nearby audience.
John had eaten bad food the night before the party so he had diarrhoea to start with. Then he drank too much at the party and started throwing up while taking a shit in the garden.
There was liquid shit and vomit everywhere and between his bursts of regurgitation, he kept yelling at everyone to help him, but everyone was too incapacitated by laughter to do anything for a good half hour.
And that, children, is the story of how John became known as the Human Fountain.
