2. Suggestion that one is a enthusiastic fellatio expert.
Project Manager to person 1: Did you not read the standards?
person 1: I didn't know those applied to me.
person 2 to person 1: You're such a tuba rockstar

or

Guy 1: I finally got that chick in accounting to come over last night.

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?"
