Lad mags are magazines that are meant for boys and grown-ups who want to read fun things and see cool pictures. They have lots of big words and pictures of pretty ladies wearing not-that-many clothes. They also have stories about sports, cars, and other things boys usually like. But sometimes, the pictures of the ladies can make them think things that they are not ready for. So it's important for grown-ups to make sure it's okay for boys to read them.
