When no 'oustide' energy is needed to initiate a reaction.

Explanation:

All reactions start by the breaking of bonds between atoms. Breaking bonds requires energy input, forming bonds releases energy.

In a spontaneous reaction, no 'extra' energy is needed to set the reaction off. Hence it occurs 'spontaneously'.
