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 cinammon roll, the roll of the cinammon? That looks like a jizz. Yeah, Eastern European jizz. That looks like some fuckhead shot his load on a $12,000 calf skin jacket. The twist is it's my $12,000 calf skin jacket. Okay so you got the semen. You got the human ejaculate that has been allowed to sink in for seven hours, into the fabric fucking fibers.
