pencil beat

A term used originally by carnival workers to describe arbitrary fees or charges designed to take away money or wages a person should be entitled to keep or receive.

Person 1: "Even with the late charge, I should have my payments caught up next month."

Person 2: "You won't pay just a late charge - after they pencil beat you for administrative and other charges, you'll be paying a lot more."

I'd rather just clean my own uniforms, rather than have the company pencil beat me for cleaning charges on every paycheck.
