It's just another cutesy sales term around here that doesn't really mean anything. This place has ALWAYS fostered used car salesmen theatrics on for sale posts...I really don't care how much you love the game but "my grail just came up!!!!" so something has to go...or that it was only played by your grandmother on Sunday mornings for the past 20 years...or that you really love the game but you need a new water heater....
Most people can read past this garbage and get to the relevant info.
