The New York Observer describes a “shmomosexual” as a “Joe Shmo” kind of guy — only gay — who’s a little too smart, dresses sloppy and is utterly untelegenic.

Joe Shmo: someone so asinine, ridiculous and absurd their mere presence bothers anyone in the room. (The Urban Dictionary)

Telegenic: Having a physical appearance and exhibiting personal qualities that are deemed highly appealing to television viewers.

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.
