- "Hookup culture"
- " hookup culture is one that accepts and encourages casual sexual encounters, including one-night stands and other related activity, which focus on physical pleasure without necessarily including emotional bonding or long-term commitment. It is generally associated with Western late adolescent behavior and, in particular, American college culture. The term hookup has an ambiguous definition because it can indicate kissing or any form of physical sexual activity between sexual partners" - Wikipedia
- Sociosexual oreintation
- "Sociosexual orientation (or sociosexuality) is the individual difference in the willingness to engage in sexual activity outside of a committed relationship. Individuals with a more restricted sociosexual orientation are less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners. Individuals who have a more unrestricted sociosexual orientation are more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness" - Wikipedia
- "The Sociosexual Orientation Inventory (SOI-R) is a 9-item self-report questionnaire designed to measure individuals differences in the tendency to have casual, uncommitted sexual relationships. This tendency, termed sociosexual orientation is divided into three facets measured by the inventory: behavior (in terms of number of casual and changing sex partners), attitude (towards uncommitted sex) and desire (for people not in a romantic relationship). The most recent revision is from 2008." - Sociosexual Orientation Inventory

- @Urban Dictionary - "Sociosexual orientation (or sociosexuality) is the individual difference in the willingness to engage in sexual activity outside of a committed relationship. Individuals with a more restricted sociosexual orientation are less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners. Individuals who have a more unrestricted sociosexual orientation are more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness.This is a rather new term I think, 2014 being the first time I have encountered it. Sociosexuality is a psychological or clinical term for promiscuity, or the degree of it, i.e. high or low."
