up
n.— «During my short stint as a car salesman, I remember how we used to stand on the curb in front of the dealership “calling ups.” “Green Toyota!” one salesman would call, claiming the driver of that car as his customer.…The salesman is always looking for the customer (they call them “ups”) with an 800 credit score and a burning need for a new car.» —“Buyers Are Liars: Selling Metal in the Internet Age” by Philip Reed Edmunds.com: Inside Line May 16, 2005.
