If you have downloaded Snapchat, watch out for Snapchat perverts. Snapchat perverts are simply older or younger males or females that have nothing to do besides ask for nudes and send pictures and videos. Be careful who you add because while you can have a lot of fun with Snapchat's filters and effects, there are thirsty people out there. Simply block them.

Snapchat Streak is accessible on the mobile app Snap chat. It is represented with a fire Emoji and number. The lowest number that you can get is 3.

You can change the fire emoji to another emoji by going to Settings---> Manage---> Friend Emojis---> Snapstreak!--->(then pick your emoji).

A stupid teenage girl who has her whole life on Snapchat. She will probably be depressed if Snapchat is taken away from her. She takes pictures/videos of everything and annoys everyone around her with her stupid social media addiction. The amount of time she spends on Snapchat daily is likely more than the average amount of time that a teenage boy spends on video games WEEKLY.
