Nail chipper
A nail chipper is a working-class person who gets their hands ruined by doing boring, rich-person jobs. They might work at a country club, a restaurant, or a fancy house. They don’t get any love, just chipped nails.
I work at a fancy club. I polish shoes all day. My hands look like they’ve been in a blender.
I’m a nail chipper. I clean up after rich people. My nails are always broken.
I work for a rich family. I cook their meals all day. My nails are chipped from doing dishes.
