macco
A macco is a dumb, skinny person who hangs out with chavs and is probably a pedo. They're the kind of person who thinks they're the best at everything.
That macco said he was the best at math. I got a B and he got an F.
My macco cousin tried to hug me in the store. I ran away.
My macco friend was in a white van with other creepy kids. He probably likes little kids.
