MurpleCow is a friend. A great one, at that. You enjoy speaking to him and spending time with him. He is overall just a kind, amazing, reliable dude, and will always be down to talk to you. He'll guide you through a rough patch in your life and show you the positive side of things. He's very handsome, too, and rocks those thigh highs. Truly a king, MurpleCow is, and you'll never regret meeting him once you do.

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.
