Here's what those mysterious emoji on Snapchat actually mean

Snapchat says a gold heart next to someone's name means you send the most snaps to this Snapchatter, and they send the most snaps to you, too.

Your best friend is also this Snapchatter's best friend.

This isn't your No. 1 best friend, but this is a Snapchatter you send a lot of snaps to.

If you see this symbol, it means one of your best friends is also one of this Snapchatter's best friends.

You're someone they send the most snaps to, but they aren't someone you send snaps to the most.

Snapstreaks are a score from Snapchat that tracks how many consecutive days you've snapped back and forth with a friend.

If both you and your friend don't both send a snap within 24 hours, you’ll lose the fire emoji — and, of course, your Snapstreak.

You and your friend have to send each other a snap — not a chat — in order to keep the streak alive.

The birthday cake will appear next to your friend's name on the date they entered as their birthday on Snapchat.

Snap doesn't include the baby emoji on its website anymore, so it's possible Snap has eliminated that symbol altogether.
