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.

sub scrubbers

No talent hacks who run a YouTube Channel, but they can't attract any viewers or subscribers of their own, so they subscribe to another popular channel in order to direct people to theirs.

Once my You Tube Channel became popular, I knew I needed a Mod to exterminate all of the sub scrubbers.

Sub-racist

A person who is racist but not enough to be considered one.

Black person: Hi, how are you?
White sub-racist: Hi, I don't like you.

sub-blogosphere

Places that are like the blogosphere, but not as creditable, like anonymous commentary threads linked to the blogosphere.

John: I was searching on Google, and it says our new employee is a sex offender.

Mandy: Let me see. Good grief, this is a chat thread where he argued with some anonymous moron. This info isn't even from the blogosphre. This is the sub-blogosphere.

Note: This word is in usage and can be found by Googling.

sub for a cookie

A catchphrase MrBeast put on his banner a long time ago. It was basically a "please subscribe" call, but it was unique to MrBeast, and it gave him some individuality and more subscribers. Now, it's essentially the default YouTuber subscribe phrase, used by generic YouTubers with no personality, and by spam channels with no originality and they are only creating YouTube videos for the money. That's why MrBeast was probably the only inspiration for them to create YouTube videos.

They're not even good videos, they are 5 second YouTube shorts with an r/funny post they've stolen.

This channel's banner says "sub for a cookie 🍪", and they only showcase memes I saw years ago.
