In brief: Fasciculation

Most of the time a muscle "twitch" (or fasciculation) is totally normal.
However, it can be a sign of nerve disease (lower motor neuron disease). If there was a nerve disease, i would also expect to have some evidence of sensory or strength loss on exam (and in the patient's list of complaints). Additionally i would expect reflexes to be reduced or absent. Without these, it is probably normal.
