An excellent digital 'linear' synthesizer from the late eighties, made by Roland. Less expensive than the D10 and D15 because it has less memory and no sequencer built in. Produces very nice phat bass and leads, although the piano and guitar patches suck.
Value of a used D5 is about a hundred dollars.

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?"

A D5 means dumbshit. So if someone is acting like a dumb shit you call them a D5.
