• Don't worry if you're perplexed because you received a blank snap with a 'S' on it; you're not alone. The 'S' on the snap, it turns out, stands for 'Streaks.' Snapchat's Snapstreaks feature ensures you don't forget about your friends. Snapstreaks happen when two people exchange snaps for three days in a row.
• To distinguish a 'Streak' snap from a regular snap, the letter 'S' is used. Snapchat streaks are all the rage. While Streaks may not provide you superpowers, they do provide you with bragging rights and a small flame emoji next to your name on your friend's account.
• As a result, if someone sends you a snap for a streak, you should keep it going. If you have already completed your streaks or plan to do so later, you may either reply with a picture or simply open it.
