When you borrow, someone fronts you something (cash, a book, a good shirt for your date on Friday night). "The borrow" is the cost of borrowing shares if an investor has to borrow the shares from the brokerage (it's called short selling a stock). The borrow is usually expensive because of the high interest rates charged.
