Werewolf

“Saw a werewolf drinkin a pina colada at Trader Vic's and his hair was perfect.” Werewolves of London - Warren Zevon

There is evidence to suggest that the full moon invokes madness in men; causing them to perform atrocious acts that they would not usually have considered.
Almost like human PMS, except more like FMS: (full moon syndrome) where human beings are apparently generally a little bit more… bitchy.

Both science and art (as well as mainstream modern cinema, see (or don’t): the “Twilight” series and the upcoming Hopkins flick: “The Wolfman”) have concerned themselves with the mythological matter of the “werewolf”, literally: man-beast; take the ancient folklore which defined the beastly transformation as: shape-shifting from human to animal when the moon is at its fullest. From the story of Ovid to the tale of little red riding hood the werewolf has been a recurring motif in art and literature, which becomes all the more interesting when the moon cycle connection is taken into consideration. As pseudo-scientific as they may be, a number of studies have shown a correlation between psychosis and the full moon suggesting that violence and general compulsive behavior are most frequent around that time of the month.

It comes as no surprise then that Lunar and Lunacy share the same prefix.
