(Australian context) A boy who goes through puberty at a very young age, and is usually the tallest and oldest looking amongst his peers between the ages of 11-
13. After that, he stops growing, and his peers go through puberty and become the same size/taller than him in the
later teenage years. Despite this, however, a manchild
will retain his characteristically mature features well into later life.
twelve year old boy1: dude, that guy over there has already started shaving. And he'
s like taller than all of us.
twelve-year old boy2: Yeah, he'
s such a man child!
(4 years later)
16-year old boy1: Hey look, it'
s the same guy we were calling a manchild 4 years ago! What happened man, he used to be taller than all of us, now he'
s like 5'9.5'' and we're all 6'1'' !!
16-year old boy2: I know, he'
s actually the same size he was when he was 12. But dude, he'
s still a manchild- look at his awesome stubble and hairy arms!
