A red heart on Snapchat signifies a "Best Friend" status.
Here's what it means:
- It indicates that you have been each other's "#1 Best Friend" for at least two consecutive weeks.
- This means you send the most snaps to this person, and they send the most snaps to you.
In short:
The red heart represents a strong, consistent friendship on Snapchat, based on the frequency of your interactions.
