Spontaneously self-combusted 

Usually said after relaying a chain of events to make them sound more interesting.

"Then I went to the computer and logged onto Facebook, and I suddenly spontaneously self-combusted."

Spontaneous Self-Combustion 

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!
