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?"

An area that is quite possibly the greatest area in California. It makes up the peninsula of the Bay Area. First founded on August 2nd, 1997 after it split from the evil area code of the 415. People from San Francisco (415) and San Jose (408) hate on the 650 because they are jealous.

Area code in the Bay Area. located on the peninsula pretty much inbetween San Francisco (415) and San Jose (408). Sometimes called "West Bay" although there's really no such thing.

Some cities cities in 650 are:
SAN CARLOS, Burlingame, East Palo Alto, Los Altos, Menlo Park, Millbrae, Pacifica, Palo Alto, Redwood City, San Bruno, and San Mateo. Sorry if I forgot some

Belmont is also in 650, although it is one of the crappiest cities ever.
I've lived in 650 since '93, in San Carlos. Hella tight area, though 619's not bad.
