It means your tounge won't move until your jaws reach 2500 rpms.
It really means that the torque convertor will slip until you reach 2500 rpms at which point it will lock up solid and spin the tires or begin moving the car.
You can "flash" the convertor by holding the foot brake and reving the engine slowly up to the point where it breaks the back tires loose.
That will give you a "rough" idea of what the convertor's stall speed is.
