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.

janyiah is pretty and laughs at everything but can sometimes be annoying and can never be serious with anything you say. She also thinks she pulls niggas.................she also likes math and is lowkey thick
