la chapa
A chapa is a woman who rules the house. She’ll help you when you’re down but if you’re a pain in the neck, she’ll make sure you know it.
My chapa got me a scholarship by calling the school and saying I was her only son.
My chapa showed up at my first day of school and told the teacher I was going to be the best.
My chapa gave me a slap when I told her I didn’t want to do my homework.
