Friendship is a relationship of mutual affection between people. It is a stronger form of interpersonal bond than an "acquaintance" or an "association", such as a classmate, neighbor, coworker, or colleague.

In popular culture, the friend zone is a relational concept, describing a situation in which one person in a mutual friendship wishes to enter into a romantic or sexual relationship with the other person, while the other does not. The person whose romantic advances were rejected is then said to have "entered" the friend zone, with the sense that they are stuck there. The friendzone has a strong presence on the Internet; for example, on Facebook, dating sites, and other social media platforms. However, over time the term has expanded into middle schools, high schools, and colleges where young people are discovering their identities when it comes to dating and romance.
