One way to get the emoji with the triangle is to paste the emoji you'd like to use followed by [triangle]. Once you hit enter, the emoji will automatically be generated. In some cases, though, users are not able to see the emoji even after they've followed these steps. If you have that issue, the easiest way to post the emoji yourself is to copy it from another comment that already exists.

Most people who post the emoji are likely copying it from another person, as that's the simplest way to post it yourself. As the trend spreads across TikTok, it should be fairly easy to find a comment featuring the emoji that you can use to participate in the trend yourself.

Of course, even if you've seen the emoji and the comment that usually accompanies, you might not know exactly why the trend is so popular.
