macco
A macco is a big-hearted idiot who hangs out with chavs and eats too much. They’re usually really skinny and still try to impress everyone.
My macco friend eats pizza for breakfast but still weighs 90 pounds.
That macco tried to talk to the principal about being the best student even though he failed math.
My macco cousin went to the store just to tell the clerk how cool he was.
