Something on Snapchat that forces other people to snap you and makes you look like you have lots of friends but in reality most pictures are of a wall or the ground. Sometimes used as a pathetic way to start snapping your crush because you have no courage at all.
A 'streak' is something you get with friends on snapchat. You send pictures to them everyday and see how long you can keep the streak going. When you get a streak, a number will be next to the persons name of how many days your streak has been going.
