The fear of a cunning backstabbing fiend. Someone so conniving that it scares you half to death. Someone you have to see very regularly, someone whose underhanded methods are done is such a manner that you will look like a complete bitch if you call her out.

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
