G child
A kid who's got no fear and a mouth like a sailor. They might be young, but don't let their age fool you. Their mom is a beast.
My cousin is a G child. He talked back to my aunt and got a black eye for it.
That kid in the lunchroom called me a f***ing loser. He's a G child for sure.
He's only 12, but he cussed me out like I was his dad. G child, all the way.
