Is a transient Tourette's-like syndrome characteristic by short outbursts of profanity, with the inclusion of politically incorrect statements and racial slurs.

A sufferer of Yorkshire syndrome must:
- Have been born in the English county of Yorkshire (N,S,E or W).
- Not have been diagnosed with any other psychological illness.
- Must have an episode (outburst) at least every-other day.
- Should feel little or no concern as to the effect their condition has on those around them.

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.
