When the voltage drop across it results in a current flow such that the volt amps (watts) exceeds the power rating for the resistor.

When electricity flows through a resistor, the resistor heats up. If it heats up enough, it burns up.

Resistors can get very hot, hot enough to burn you and ignite rocket engines. But I doubt that they blow up with a bang, with the exception of immense discharges

They are subject to a voltage that causes too high a current to pass through them. The resulting excessive power will melt their resistive element.
