Etymology

Origin of puerile

1650–60; < Latin puerīlis boyish, equivalent to puer boy + -īlis -ile

Explanation

Some people like their movies to have sophisticated humor and others prefer the more puerile humor of pratfalls or jokes about smelly underwear, inappropriate belching, and passing gas. Although the adjective, puerile can be used to describe anything related to childhood, more often than not, it is used in a derisive manner to comment on the immaturity, silliness, or juvenile nature of something or someone. So if you hear someone talk about puerile toys, they may merely be remarking on the toys of childhood, but it is more likely they are discussing whoopee cushions, fake dog poo, and the like.
