a kid that is waiting for their 13 birthday to come so that older teens won’t be able pick on them anymore for their age on the internet. sometimes these 12 year old CAN be a hardcore show-it-off to teenagers OR they can be really chill. since they are close to their teenaged lives, they have a sense of matureness most times.
person 1: “hey is that jaquelin?”
person 2: “yeah but isn’t she a 12 year old?”
person 1: “yeah so? she’s pretty chill
person 2: “you right.”

Simply somebody who has been alive for 12 years. No insults needed.
Person A: Hey look at that 12 year old! Of course it's another one of those idiots who think they're so cool.

Person B: No need to insult them. They can't automatically change their mind. You shouldn't say that unless you want to be pathetic.

A person who is 12 years old. Sometimes used as an insult on the internet by older people who were probably really stupid 12 year olds and figure that everyone else must of been as stupid and pansy-ish as they were when they were 12.
Guy 1: Well the earth isn't flat really as science clearly already proved its sphere shaped.
Guy 2: And you're just gonna follow anything that science says? You must be a 12 year old or just stupid in general.
Guy 1: --_--
