A harmonygasm is the experience that people (mainly those involved in musical theatre) experience when hearing a very intense harmony in a song. Harmonygasms can result from harmonies in all music, but usually they result from contemporary musical theatre songs that include belted harmonies. Harmonygasms usually give the harmonygasm-er chills, intense joy, shaky hands, and a rapid heart beat, as well as an intense love for the music giving the person the harmonygasm.

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.
