A few references about sex and porn have been contained in this movie.

The young couple have an anal sex at the room. Only the boy's bare chest is visible. The moaning noises can be heard from the girl. No female nudity is shown as she wears a long t-shirt for her top(Camera only focuses her upper body). No genitals are visible. However sex is implied.

A couple of kissing scenes between two different young couples, nothing passionate or sexual.

There are several F bombs

Good couple of jump scares throughout the film. Very predictable ones, however.

Clowns used as a nod to Stephen King's IT.

The film is frightening throughout.
