Naggard
A Naggard is a woman from the ghetto who thinks she's the only one who knows how to nag. She nags people until they beg for mercy.
'You didn't do your homework? I'm gonna nag you about it until you pass the test.'
'Why did you forget my birthday? I'm gonna nag you about it for the rest of the year.'
'You didn't clean your room? I'm gonna nag you about it until you're ready for bed.'
