Since a great deal of primate behavior was considered just awful, most of the domesticated primates spent most of their time trying to conceal what they were doing.

Some of the primates got caught by other primates. All of the primates lived in dread of getting caught.

Those who got caught were called no-good shits.

The term no-good shit was a deep expression of primate psychology. For instance, one wild primate (a chimpanzee) taught sign language by two domesticated primates (scientists) spontaneously put together the signs for "shit" and "scientist" to describe a scientist she didn't like. She was calling him shit-scientist. She also put together the signs for "shit" and "chimpanzee" for another chimpanzee she didn't like. She was calling him shit-chimpanzee.

"You no-good shit," domesticate primates often said to each other.

This metaphor was deep in primate psychology because primates mark their territories with excretions, and sometimes they threw excretions at each other when disputing over territories.

One primate wrote a long book describing in vivid detail how his political enemies should be punished. He imagined them in an enormous hole in the ground, with flames and smoke and rivers of shit. This primate was named Dante Alighieri.

Another primate wrote that every primate infant goes through a stage of being chiefly concerned with biosurvival, i.e. food, i.e. Mommie's Titty. He called this the Oral Stage. He said the infant next went on to a stage of learning mammalian politics, i.e. recognizing the Father (alpha male) and his Authority and territorial demands. He called this, with an insight that few primates shared, the Anal Stage.

This primate was named Freud. He had taken his own nervous system apart and examined his component circuits by periodically altering its structure with neuro-chemicals.
