The term, which originated in the United States in the 1990s, is the male equivalent of the more common slang - fag hag, a term which is part of hag-ism; the identification of a person with a group—usually united in terms of sexuality, gender identity, or shared sex—of which he or she is not a member.
Mainstream shows, such as Queer Eye for the Straight Guy, Queer as Folk, Will & Grace and others, often explore the mainstreaming of friendships where differing sexualities play a complement rather than impediment to friendships and social situations.[dead link]
In addition, homophobia has become less prevalent, and efforts to confront violence and hostility towards sexual and gender minorities, such as gay-straight alliance has helped lift some of the stigma attached to having LGBT people as close friends.[dead link]
When Radar magazine debuted, its founder and editor-in-chief, Maer Roshan, called competitor Details' editor-in-chief Dan Peres, a "professional fag stag," stating, "Let's get one thing straight, Peres is not gay. But, his magazine sure seems to be."
An alternate use of the term fag stag, is a male gay icon celebrity, who is thenselves either straight or gay, and is loved by the gay community, and has "gay buddies," such as: Kevin Smith, Ben Affleck, Eric McCormack, Justin Timberlake, Colin Farrell, Matthew Broderick, Robbie Williams, Ben Cohen, Darren Criss, or Daniel Radcliffe.[dead link]
