All forms of bullying! Men have advocated and encouraged this old abuse to kids, their own kids, forever, and it's a cruel, sick practice at home, at the kitchen table, and it should be permanently put out of its misery. All bullies are cowards, all bullies are having big problems with their own lives, and we're not talking about great intelligence here or the vision of a great future. It has been promoted like something precious in too many families  waaay tooo long.
