Definition:

The act of making your bed using all 4 limbs once already under your blankets. This is because you are either too tired or cold to get back out of the bed and fix your sheets the right way.
Examples:

"I was too tired to make my bed before I went to sleep. So once I got in I just 'hot stacked' it instead."

"My girlfriend gets mad at me when I 'hot stack' the sheets and blankets."
