Gayfax. Coupling of the words "Gay" and "Facts" to describe something that both carries the weight of truth, and is fucked beyond measure. (See Trufax)
From "kayfabe" (a term used in Professional Wrestling and carnivals, meaning a "work") an act of feigning gayness, so as to manipulate or contrive social situations. Commonly, a straight man pretending at being gay so as to curry the favour of real gay men, or to better position himself in romantic interests involving women who are known to rebuke the advances of heterosexual men.

Gayface is the look that gay men have that enables other gay men to quickly identify them as "family" no matter what they're doing, wearing or saying. Gayface is identifiable in photos. Gayface cannot be hidden by attempts to butch it up. Straight men with gayface are not really straight.
