A heterosexual woman, esp. a celebrity, who is revered by lesbians.
Tina Fey, Mariska Hargitay, and Pink are all dykons.

Any celebrity or cultural icon (almost always a woman) who is popular among lesbians and considered a gay icon.
Xena, Gina Gershin (Showgirls) and Mariska Hargitay (Law & Order: SVU) are all dykons.
