See also Open marriage.
An open relationship denotes a relationship (usually between two people) in which participants are free to take other partners; if the couple making this agreement are married, it is an open marriage. While "open relationship" is sometimes used as a synonym for "polyamory" or "polyamorous relationship", these terms are generally differentiated. The "open" in "open relationship" usually refers to the sexual aspect of a non-closed relationship, whereas "polyamory" refers to the extension of a relationship by allowing bonds to form (which may be sexual or otherwise) as additional long term relationships:
However, there is enough overlap between the two concepts that 'open relationship' is sometimes used as a catch-all substitute when speaking to people who may not be familiar with 'polyamory'.
The social network service facebook.com allows users to set their status as "in an open relationship."
