I don't know what the hell "eggy" means, other than covered in egg. Maybe you had a stroke and didn't realize it.
Like transy without insinuating someone being outright trans. Metaphor for closeted trans folk, when they come out they "hatch" from said egg.
It's nothing like that, though I have actually considered it. It's more of a commitment to not conforming to stereotypes. I've never felt uncomfortable as a male or thought I should have been born female. I just don't care about adhering to behavior patterns considered to be masculine. Keeping all options open, basically.
