The term 'Cause for an R Rating' refers to the content of a movie or other media that is deemed too mature for younger audiences. This content can include SEX and GORE, which are two of the most common reasons for an R rating. SEX is defined as any activity between two or more people that involves physical contact or sexual pleasure, while GORE is defined as the depiction of violent or gruesome scenes. Both of these elements can be found in movies and other media that receive an R rating.
