WHAT DOES THISMEAN?

I opened TikTok on my computer and almost EVERY comment section has some comments with this phrase either alone or before another message. Is it a sticker? Other stickers don’t show as well on TikTok on the browser/computer, but those just say [sticker]. What is this?

Im pretty sure its supposed to be an image comment. You cant see those on web tiktok and for whatever reason theyre represented by that text
