Someone might say, “Omg, I was at dinner with my boyfriend and my ex showed up 😬” or, “I thought Melissa was waving at me, so I waved back, but she was saying hi to someone behind me 😬. ” Some people call the 😬 emoji the teeth or tooth emoji. That’s actually this emoji, though: 🦷 (tooth emoji).

You can tell they’re your best friend because a 💛 (yellow heart emoji), ❤️ (red heart emoji), or 💕 (2 pink hearts emoji) will appear next to their name. The 💛 indicates you just became best friends. If you stay best friends for 2 weeks straight, it becomes a ❤️ emoji. The 💕 appears after 2 months of friendship.

Don’t take this the wrong way. Even if someone is snapping your best friend super often, it doesn’t mean they’re sharing anything serious. It’s even possible your best friend isn’t replying.

If either of you were to drop Friend #1 as your best friend (either intentionally or unintentionally), that 😬 emoji will disappear.
