The active ingredient in asprin and one of the ingredients in Alka-Seltzer. Acetylsalicylic acid (or its various translations) may be used as a generic term in countries where Bayer's trademark claim to asprin was not invalidated after World War I (e.g., Germany, Canada, Mexico).

The term may also see use where it is desired to refer to the pure chemical, as opposed to any medical formulations. It may also see use where the person saying it wants to sound scientific or very intelligent.

I took some acetylsalicylic acid for my headache.

Acetylsalicylic Acid

The scientific term for Aspirin. In many countries, notably Canada and Germany, "Aspirin" is a patented trademark of the local Bayer subsidiaries. Any non-Bayer products are labelled with the abbreviation ASA (Canadian English), AAS (Canadian French), and ASS (German). I am not making the last one up!

The term Acetylsalicylic Acid, in its entirety, is rarely used in layman's conversations.

Just as many people refer to any tissue as "Kleenex," Canadians often refer to non-Bayer ASA as "generic Aspirin" or, simply, "Aspirin."

Whale

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.

"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."

city chicken

A food native to Pittsburgh/Western Pennsylvania in which cubes of pork and/or veal are put on a short, wooden skewer, breaded, then baked and/or fried.

I've heard that city chicken originated during the Great Depression, when folks didn't have enough money to buy full cuts of meat, so they assembled meat scraps on a wooden skewer, creating a make-shift drumstick. Hence the name.

Are yinz havin' city chicken for dinner?
