There is no definitive answer to this question as it is entirely dependent on individual users and their preferences. However, some tips that may be useful in finding a user's #1 BFF on Snapchat include:
- Checking who a user snaps the most frequently
- Checking who a user has added to their Snapchat Best Friends list
- Checking who a user has added to their Snapchat Close Friends list
If all else fails, users can always reach out to their friends directly and ask who their #1 BFF on Snapchat is.
