Memegendered 

Someone who claims to be any gender other than male or female.

It might be a real gender or it might not exist, I don't fucking know.
Other "genders" are often joked about in memes. That is where the word comes from.

It comes from the "There are only two genders," meme. Anything other than the first two generic genders would be a memegender.

If you knew that I was bullied in the third grade for being a refrigerator door handle would you be saying that? I don't know, after all, you're just a misogynistic homophobic transphobic xenophobic memegendered sexist pig. (From user: ImportedSocks, 2016)

When a group of SJW's feel triggered by masculinity, they organize a memegender; that is, they collectively double the dosage on their female hormone injections to ensure that no one in the group will express any overt masculinity. During an emergency memegender, some SJW's will actually castrate themselves.

When Andrew Dice Clay came out of retirement we organized an emergency memegender.
