"Do you have your Slave Card with you?"
by New Rising Sun August 9, 2005
some stupid yet miserable guy who was seduced by bank promotions and finally got sunk into huge credit card debts, usually a post-80s urban salaryman or salarywoman deluded by middle-class dreams.
"...our thrival depends on our capablity and efficiency in developing a card holder into a card slave, or more formally, our life long loyal client..."
