Someone who is both a gay man and a lesbian! Yes this is a valid identity, there could be many reasons someone identifies as this, one of which is mentioned below
Person 1: Hey you know how I'm genderfluid and my sexuality changes depending on my gender (a form of abrosexual)
Person 2: Yeah?
Person 1: Well, I've realized that whenever I'm a man I only feel attraction to men and never women, but when I'm a woman I only feel attraction to women and never men, making me gay when I'm a man but lesbian when I'm a woman. So! I decided to use the label gaybian to explain my experience :)
Person 2: Woah that's so cool!
The act of telling ur friends you are on you're way to said establishment, having no intention at all of even showing up let alone even leaving you're house..
Committing to going places with you're friends, but not even leaving you're home and telling them that you are almost there.
Dude did you call Ryan and ask him if he was coming?
Yes, he said he's on his way.
Right, I'm sure he's pulling a Gayman on us again.
