I would never name my child Jason Voorhees.
Wooded lakeside camps have always been forlornly creepy.
Silent giants wearing hockey masks out of context is now nightmare-inducing.
But calendrically there's nothing inherently scary about Friday the 13th. The date is arbitrary. It could have been "Tuesday the 27th."
[insert Wilhelm scream here!!!!].
