Casual Relationship

A Casual Relationship, also called Friends With Benefits (FWB), or No Strings Attached (NSA), is a friendship that includes sex, sexual activity, and sexual intimacy, but is not romantic in nature and typically does not have the same degree of expectations, commitments, or investment typically found in a formal romantic relationships. Those in such a relationship consider their bond to be platonic but with occasional casual sex involved.

History
The term 'friends with benefits' is speculated to have first been used by Alanis Morissette for her 1995 song “Head over Feet”, although in the original context it seems to refer to a committed relationship rather than a casual relationship. Since then, the term has been used to describe what it is now today.
