SC question???💛

I’m definitely more savvy when it comes to social media I use Instagram more. My bf was showing me something on his phone and he had Snapchat up. There was a 💛 next to a girls name so I asked him who that was. He said it was a girl from school he had just added a few days ago.

How often do you have to been snapchating someone in the span of like 2 days to get a 💛?
