Wire coils with a current running through them are used for degaussing (demagnetizing) things. An extension cord when used and left coiled creates a magnetic field making it a degaussing coil. This can increase the amount of resistance in the cord, causing it to get warm or even hot.
If the amount of current you are using is low then you'll be okay. But when using larger amounts of current for a longer period of time such as a microwave running at the same time as other 120v draws or running an air conditioner, the cord can get hotter than if it was uncoiled and lying in a pile. If left coiled, you might check it periodically to make sure it's not getting too hot and becoming a fire danger.
