Pimping agency - staffing or employment agencies that treat you like a dog, make lots of money off of you, and pay you next to nothing in return ... (in my opinion).
A pimping agency treats their workers like dogs. No matter how bad the place is that they send you to work, you have to suck it up, do a good job and not complain. A pimping agency gives you no paid vacation, no paid holidays, no paid sick leave, no benefits. They rake in lots of money from your hard labor and pay you next to nothing. Note: Not every staffing or temporary agency is a pimping agency, just most of them (in my opinion).
