Ask my 5-year-old right now. I'm currently the "meanest mommy ever."
I take great pride in that.
my mother was the meanest, strictest mommy in my school. She was a substitute teacher in my district, frequently subbing at my school. I never had her sub for my teacher, but my brother did. She left teaching when they took her ruler away from her, the one she used to thwack the students who didn't listen to and obey her. Everyone said she was the meanest sub evah! I told them she was the same way at home. My school friends were horrified.
She took great pride in her reputation as a "don't mess with this substitute" teacher. She actually taught when she subbed. Most subs are glorified babysitters who are lucky if they get the attendance correct because the kids won't sit in their assigned seats, answer for each other, and test the sub in every annoying way possible. When a class saw her at the front of the room, everyone did what they were supposed to do. That ruler hurt!
