Define 9 Year Old Meaning

PewDiePie subscriber.

It is what soldiers of the Pewdiepie army are called. They were previously called as Bros, Sisters, Sister Sqaud, Squad and are now 9 year olds. True 9 year olds are those who did their part, such as Mr.Beast. Do your part, and subscribe to pewdiepie

A boy who plays Call of Duty and tells his mom to bring him energy drinks, then cussing her out for bringing him Red Bull instead of Monster, then cussing you out incorrectly for shooting him.

A 9 year old is a wild beast. they can usually be found:
*Infesting Fortnite, trying to get a close-range kill with a sniper rifle.
*On Youtube, making a 5 subscribers special.
*Playing Minecraft, screaming ear-piercingly loud about how they found diamonds.
*Hiding in Roblox, waiting for someone to come out of the museum in jailbreak.
*Dabbing. this is actually the most common activity of the wily 9 year old.
*Trying to make friends on Animal jam, unaware that the game would be dead if national geographic didn't sponsor it.
