1. The number between 20 and 22.
2. The age that you are legally allowed to drink and go into bars and nightclubs.
3. The sum of 9+10, according to a dumbass overplayed video on a popular mobile app called Vine, which lets people create quick 5-7 second videos and post them. The video goes like this.
Teenager: you stupid
5 year old boy: no I'm not.
Teenager: what's 9+10?
5 year old boy: ... 21?
Teenager: you stupid.
The original video has been made fun of all over the internet. People do remakes of it, have added the little boy saying "21" into popular videos, and have created songs about it, usually taking the beat of Bobby Shmurda's "Hot Nigga". It was on the news that the kid ran away from home, because he was sick of being made fun of.
Go up to anybody and ask them what's 9+10 and they will answer 21.
