1: A green semi-precious gemstone.

2: A character from Steven Universe, an animated television series on Cartoon Network. She has a green peridot stone embedded in her forehead, green skin, and yellow hair suspiciously similar to a Frito Lay chip. She was orginally evil and intent on using a bio weapon of sorts to explode the Earth, but eventually was converted to the Crystal Gems. She still retains her stubborn, egotistical and annoying personality, as well as her love of calling everyone else a "clod."
1: Wait, is this a Peridot or an Emerald?

2: Peridot really needs to stop calling everyone a clod.

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?"
