A blurb from the paperback bestseller Teenage Jungle (1957):

Here is a frightful indictment of youthful crime and vice in the U.S.A. It shows how the violence and sex-crazed teen-age cult exists in a living nightmare of ruthlessness and depravity.
These are ordinary kids you read about every day of your life—“ordinary,” that is, until they shoot a store-keeper, assault a girl, torture a bum or wind up dead in a ditch.

In ’57 torturing bums was like doing the Macerena. As ever, those passing fads are so embarrassing in retrospect.
