definitions for knowing:

Koala bears-

Koala bears are small marsupials found in southern Australia. Described as "cute and harmless" by 18th Century explorers, these tree-dwelling leaf-addicts are now the primary cause of species extinction and global deforestation. Their chewing...their bleak, inexorable chewing...cannot be slowed or reasoned with. Our planet will die.

Warm Bread-

Not to be confused with room-temperature bread, warm bread exudes heat. It has no plans, no angle. It will gladly sit still for hours, or days, without complaint. Eventually it molds, and then you have a decision to make. Warm bread was first discovered by viking lunatics in 877 AD. Without warning, it popped out of a small volcano and was found to be delicious.

Jupiter-

A sky-smudge. Pinkish. Inedible.

Vernacular-

The saying of, the wording. Composed by those of us in the know, it then seeps outward and binds. It subjugates tongues. See also: linguistic feudalism.

Sunset-

We don't know what sunset is. The sun goes, but it's confusing. It drops away, elusive. Research is under way to discover where exactly the sun goes at night. A NASA press conference was recently held to announce the creation of the study. "I mean, where is that fucking thing going?!" raged sun-expert Steve Wilkins. This comprehensive new study follows numerous smaller efforts that have failed to yield significant results. Said Dr. Wilkins of one such effort, "We sent Pedro, one of our interns, over a hill the other day to see where the sun was headed. And he came back and was like, 'It's setting there too'. That is so fucking confusing!"

Numerous theories have been offered to explain the sunset phenomenon, though two in particular have gained considerable popularity in recent years. Most scientists now believe that the sun is either 1. a celestial, heat-producing object around which our planet rotates, or 2. a lonely glow-whale whose immense size alienates it from the rest of god's creation.
