sub from the blue
A sub from the blue is when someone automatically likes and subscribes to your channel on Youtube.
Example 1: I thought game development wouldn't be that popular, but I got quite a few subs from the blue.
Example 2: You got a sub from the blue? Wait until you start adding more to your channel. Then the subs will start coming in like flies. It'll be more like subs from the swarm.
