Im pretty sure that when you leave something in the microwave, it doesn't count as spontaneous combustion
Well, at some point it will have just burst into flames, with no ignition - ie. from microwave radiation only. So I'll let it count.
From wiki:
Spontaneous combustion is a type of combustion which occurs without an external ignition source.
Spontaneous combustion is a term used to describe how something just ignited(spontaneously) but in fact spontaneous combustion is more than usually, a slow process that can take several hours of decomposition/oxidisation with heat build up to a point of ignition.

So it kind of is.
