Pointlessnism

Pointlessnism is an early 21st century movement began by a group of Canadian artists and thinkers. The figure head, S. Valdez, advocated the liberation of thought and action, contending that any set of actions was equally as meaningful as any other since the perception of consequence is illusory.

When S. Valdez was questioned about pointlessnism by certain skeptics, he famously went into a Superstore, bought a bag of frozen fish sticks, dumped them into a fish tank full of water in the parking lot, and began throwing them into traffic.
