taxi queen
n.— «Teenage girls are being used by unscrupulous taxi operators in Chatsworth as “scouts” to identify potential robbery targets. The girls—many of whom are addicted to drugs—are planted in taxis to identify passengers carrying large sums of money. Referred to as “taxi queens,” they point out the targets to the driver or conductor and are rewarded with cash to feed their addiction.» —“’Taxi queens’ scout for potential robbery targets” by Teneshia Naidoo Times (Johannesburg, South Africa) Jan. 19, 2008.
