What do the new emoji mean?

I've been a fan of emoji for many years, and every year I love seeing the new ones get released. They enter our phones and most of them are pretty descriptive, but you never know how people will adopt them, which of them will hit meme status, and ultimately what their meanings will entail.

To help quantify that scenario, my spouse, who is a psycholinguistics researcher that studies language, decided to start a quick survey just about the new emoji.

If you have a few minutes today, can you help us out and take the survey and give your take on the new faces of emoji in iOS 12.1?
