'Cause i can never find the original definition for this great concept, here's the complete quote:
Kipple is useless objects, like junk mail or match folders after you use the last match or gum wrappers or yesterday's homeopape. When nobody's around, kipple reproduces itself. For instance, if you to go bed leaving any kipple around your apartment, when you wake up there is twice as much of it. It always gets more and more.
There's the First Law of Kipple. 'Kipple drives out nonkipple.' Like Gresham's law about bad money.
No one can win against kipple, except temporarily and maybe in one spot, like in my appartment I've sort of created a stasis between the pressure of kipple and nonkipple, for the time being. But eventually I'll die or go away, and then the kipple will again take over. It's a universal principle operating throughout the universe; the entire universe is moving toward a final state of total, absolute kippleization.
