Annoying little shits that act like they’re 5. They are too young to do things, but old enough to make right decisions
15 year old: “Yo bro that kid is trying to fit in with us.’’
17 year old: Who? The 9 year old?
15 year old: Yeah

A special kind of specimen who specifically devote their lives to following a certain god known as Pewdiepie. As part of their cult, you must spam other channels with cringey comments carrying their lord’s message and also supporting Pewdiepie through thick and thin.
Person 1- Hey, do you watch Pewdiepie?

Person 2-Hell yeah I do, I’m part of the 9 year old army

The traditional army of Pewdiepie, our lord and saviour. As soon as one of the 9 year olds turn ten they go straight to Ali A. The 9 Year Old Army is sworn to defend their king against the armies of the evil corporate entity; T-Series. As of the publishing of this definition, the 9 year old army has approximately 88,393,093,230 troops.
I am a sworn member of the 9 Year Old Army
