spontaneous combustion 

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.
