I know I've seen multiple users with these icons on various platforms, but I've only just today realized it's a Picrew template (and what Picrew even is). It was made by an artist called Sangled (as seen watermarked in most of the icons made from it). Many of them represent their LGBT identity with a flag like the original above, but I'm seeing a lot of Twitter users hating it because Sangled is apparently "aphobic" (and if I have to define that, you are too, god dammit), not to mention it's just overused to shit. I'm outside most demographics that would have context or insight on this thing, but it probably needs an entry (I know I needed it just now). There aren't many images on KYM with it that I've found, but here are some:
