Resistentialism
Resistentialism is a jocular theory to describe "seemingly spiteful behavior manifested by inanimate objects", where objects that cause problems (like lost keys, a malfunctioning printer, or a runaway bouncy ball) are said to exhibit a high degree of malice toward humans. The theory posits a war being fought between humans and inanimate objects, and all the little annoyances that objects cause throughout the day are battles between the two.
