The euphemistic nature of the phrase is believed to have been established in mid-2014,[3] and by the end of the year had spread throughout the African American Black Twitter community, as seen by many now typing chill within scare quotes. In April 2015, a definition of the phrase was added to Urban Dictionary stating that it meant "code for two people going to each other's houses and [having sexual intercourse] or doing other sexual related acts".[1][3] Soon, the term would spread beyond Black Twitter, becoming an internet meme, gaining the attention of news websites such as The Guardian[3] and the Daily Mirror.[4]
