Helicopter Parents

I just ran across a term that I had never heard before: helicopter parent. I know what these parents act like and look like, but I didn't know there was a term for them. When I was proctoring exams, I even saw them in the hallway outside the room where their child was taking the entrance exam to medical school! Here's a definition of helicopter parents:

Helicopter parent is a colloquial, early 21st-century term for a parent who pays extremely close attention to his or her child's or children's experiences and problems, particularly at educational institutions. These parents rush to prevent any harm or failure from befalling them and will not let them learn from their own mistakes, sometimes even contrary to the children's wishes. They are so named because, like helicopters, they hover closely overhead, rarely out of reach, whether their children need them or not. Some college professors and administrators are now referring to "Lawnmower parents" to describe mothers and fathers who attempt to smooth out and mow down all obstacles, to the extent that they may even attempt to interfere at their children's workplaces, regarding salaries and promotions, after they have graduated from college and are supposedly living on their own.
