Common slang for Vigorish, or simply "the vig," which is the
fee--usually a percentage--charged by a bookie on all bets. Another term commonly used to
mean the same thing is "the take."
According to Wikipedia, vigorish is derived from Yiddish slang originating from the
Russian word for "winnings," vyigrysh. Bookmakers use the concept of a vigorish to generate earnings from their books regardless of the outcome of the event being
bet on. However, there is no standard formula for calculating vigorish though they are generally formulated so the bookie receives equal action on both sides of the event, therefor having a "balanced" book.
In the U.S. "the juice" can also refer to the interest on a loan/debt--generally in relation to a
loan shark.
With a 4.55% vig, the
juiced odds require a gambler to lay $110 in order to win $100, while using
fair odds the gambler only has to lay $100.
You've got until Friday to pay up; meanwhile, the juice is
running.
