To spontaniously burst into flames
Wouldn't it be cool if that person just spontaneously combusted?

a random and sudden outburst of laughter
Suffering from spontanious combustion usually stems from nervousness or excitement.

This girl in dentention was given almost 2 months because she went into a spontanious combustion situation.
