The act of sending an lengthy email chain to a recipient with vague directions to "see below" or "please note" without providing further instructions. This forces the recipient to search through a long list of email correspondences in hopes of figuring out what you're referring to (i.e. searching for a needle in a haystack).
"I just received an email from Dan saying 'Please advise'. But there are, like, 50 emails below his. How am I supposed to know what he's referring to?!? UGH! I hate it when he haystacks! I'm going to start haystacking him back just to piss him off."

The city of Hayward, California. It is known as the "heart" of the bay. The city was founded by a man named William Hayward, who came to California to seek his fortune in the California Gold Rush (Began in 1848, I believe). He bought some forty acres from some Rancher, and in a few years sprouted into a town. Was at one point misspelled into "Haywood". Haystack is a slang term when reffering to this city.

The term, "Haystack" is used as a name for a food often served at vegetarian and vegan lunches and dinners. It usually consists of Frito's (or whatever chips desired, often smashed), beans, lettuce, tomatoes, onions, sour cream, salsa, and cheese (often times a vegan supplement is used). This dish is most commonly served at Seventh-day Adventist schools and potlucks. But it's really just a taco salad.
"I am craving a haystack!"

"What's a haystack?"

"The Adventist version of a taco salad."
