Aug 11 Word of the Day

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.

"My boyfriend has a total case of brain worms. He told me the cat was bugged so the Feds could listen in on us having sex..."

or

"You totally stumbled over that entire sentence. Can't speak English all of a sudden? What, do you have brain worms?"

Get the 4 neck gaiter and mug.

A number which is considered extremely unlucky in Chinese and Japanese culture. The pronunciation of the character for "death" sounds like that of the number four in both languages, making it a number rarely seen in hospitals (or pachinko halls).

In Japan, more people on average die on the fourth day of the month.
