A Broomstick Prick is someone who uses the Oppressor Mk 2 in Grand Theft Auto, and often hates fun and will stop at nothing to stamp it 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.
