A somewhat fuzzy definition of entropy is as follows: the universe’s tendancy towards getting more random and chaotic, not less.
Basically, things fall apart. Like my house, where there is a particularly strong entropy field hanging over everything. Or my filing cabinet, which seems to be the center of the field. Or my life, which has already spun irrevocably out of my control.
Remember children, rollercoaster rides are only fun because you know what the outcome is going to be.
