The 69 Rule applies when you have a streak with someone on Snapchat. Every time a streak gets to 69 one of the persons with the streak must point out that they have hit 69 days. The other person must then respond with a nude and then for the rest of that day you must send only nudes until the streak is lost or moves to 70.
Person 1: Hehe, we hit 69
Person 2: Haha yeah we did
Person 1: Don’t you know the 69 Rule
