Getting really mad all of a sudden and doing something regrettable. AKA flying off the handle.
Sometimes I feel this urge for spontaneous combustion, but then I try to think to myself, "how will this fix the situation" and "what if I hurt someone, or do something very regrettable." I try to do something else instead, like take a walk or maybe play some basketball or play Halo.

The occassion when a human being may spontaneously burst into flame with no external interference. Generally happnes to the aged. Most victims do not survive, and combust when alone. Therefore, there are not many witnessess to spontaneous human combustion, or S.H.C.
However, there have been people who have suffered S.H.C and survived, albiet for only a short while afterwards.

S.H.C does not tend to leave much in the way of bodily remains; most victims leave just the lower leg, a singed hole in the floor, and a pile of greasy ash.
Reasons for this are still only theories, but the extreme heat required to reduce a human body to ash in the space of minutes is intense, and the flames act unaturaly.
In one such case, an elderly doctor spontaneously combusted whilst at home alone. When found, his kneecap and ashes where in the basement, and his foot and slipper left on the lip of the hole on the floor above. His aluminium walker, that should by all means be a puddle of molten metal, was fully intact, including the rubber tips.

S.H.C is not a proven phenomena, and is not a recognized cause of death.
The old doctor apparently died when he spontaneously combusted. Many blamed the phenomena, spontaneous human combustion for his unnatural death.

Spontaneous Self-Combustion is a more formal way of describing the act of spontaneously self-combusting. A more graphic description of Spontaneous Self-Combustion is where a flame inside the body bursts into a flaming outbreak, consuming the body and possibly the surrounding area.
The concept of Spontaneous Self-Combustion first appeared in writing in a Charles Dickens novel. Could the idea be linked with vampirism (burning in light), love (an internal flame of love) or smoking (accidentally inhaling/swallowing lighters, and/or fuel - don't try that at home, or anywhere for that matter)?
The practicality of Spontaneous Self-Combustion is questionable; can a human (mostly made of water) really spontaneously self-combust? Not that I am trying to taint the fun, or anything.
Spontaneous Self-Combustion is a fairly surreal concept to most, so fire-proof underclothing has not yet become necessary. Not yet.
As the person innocently wandered down the street, an internal flame grows into a rage and eats at the mortal remains. It was most unjustified!
