n. pyoo-muhn:
literally, a pig-human; a grotesque human being; the lowest form of life on earth

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.

A puny Human who is part of the puman race

A human, usually female, posessing the sensual, feline, predatory qualities of a puma; generally self-sufficient and fiercely independent. Physically lithe.
