HAGGWITCH
A crumby, grumpy, old lady (hag) with witch powers to not care about anything or anyone, even if they try to murder her.
My neighbor is a haggwutch. She yelled at me for mowing my lawn on a Tuesday.
My mom is a haggwutch. She doesn't even care if I fail school.
My teacher is a haggwutch. She failed me for eating a donut during class.
