Slave driver – a slave minder. A parent, teacher, or boss who stands over their souls with an imaginary whip (sometimes a real one) and makes them work hard.

It's not hard to guess where this expression has its roots, and who might be greatly offended if you mention "slave driver" in their presence. Yet to the white boss from the white subordinate will sound quite on topic: they say, look what a despot, going back and forth, shooting his eyes, shoot, so that no one at work on the cat in Insta did not look. Coz of these characters, people run from offices to work at home like crazy.

Example:
- Our teacher is a real slave driver. He hits us with his pointer as if it was a whip.
