In olden times, the master of the house used to sit out on the porch in nice weather where it was shady and there was more of a breeze than there would be indoors. The servants who attended to the master's needs could often be found beside him/her on the porch. Because people didn't have telephones or many places to go to socialise, the master and his family would often entertain guests and engage with passers-by on/from the porch. "Monkey" has been a derogatory slang term for a black for centuries. That's where it started. Many people in the American South still while away the hours on their porches today.
It was a term for a child slave who worked in the house instead of the field.
