Possibly the coolest affliction known to man, projectile vomit occurs only after you've done a very very bad job of taking care of yourself. Stomach acids and other half digested foods have been known to fly 3 feet and further. This should really be considered as an olympic event.

Certain members of the animal kingdom, including the turkey vulture, Cathartes aura, and the Northern fulmar, Fulmaris glacialis, have been known to projectile vomit as a defensive strategy.

On the ground, the vomit may distract or repel predators. One side-effect of the expulsion of the stomach's content is that the bird weighs less, making escape via flight easier.
