single father who gets to see his kid/s on saturdays - usually has over spoiled the kid to catch up for the lack of attention in the week - often seen in England

1.
a divorced or separated father whose work schedule allows him to take custody of his kids only on Saturdays
He takes his kids to Playland, suffering the over-crowded, sticky-candy, ride-barfing fun - like the good Saturdaddy he is.
