Lunatic

The word lunatic is derived from the Latin word luna which means moon. A lunatic is a person who is affected in a negative way by the full moon. Remember the werewolves? Vampires?

Now you know where the legends come from. Historically, some people really do go berserk during a full moon.

Police crime statistics have shown that there is a spike in crime during full moon days. Just take note of the next full moon weekend.
