It will continue to slowly boil as energy from the room enters the cup in the form of heat. So as it boils, the liquid cools until it reaches the equilibrium that is it's boiling point at the pressure of the room (about -25 degrees C). But boiling takes energy, and this energy (think: heat of vaporization) comes in the form of temperature from the surrounding. As such, it begins to boil when it is released from the can. This liquid can be thought of similarly to liquid nitrogen: it is a liquid that cannot exist at room temperature and pressure because it's boiling point at standard pressure is much lower than room temp.
