%

Percent; amount per hundred. A concept which many people are somewhat naive about.

Also used in many computer codes for variables, or for encoding special characters in web addresses.

1% = 1/100 = 0.01 ; 100% = 1

Why do some coaches ask you to give it 110%, when 100% is (by definition) the most you can give?

The code for a % sign in a web address is %25.

°

"Degrees"; the "degree" sign. Commonly used in temperatures, angles, and geographical coordinates, it can typed on a PC by hitting Alt-0176 (using the numeric keypad), and its HTML code is °. I wouldn't be surprised if someone's used it in a job advertisement before.

It was 92°F (33°C) outside today.

There are 360° in a circle.

Hlp wntd, PT/FT, $8-12/hr, no ° req.

floppy floppy

An old-fashioned 5.25-inch floppy disk, commonly used in early personal computers (such as Apple IIs and IBM PCs). So nicknamed because, unlike 3.5-inch floppies, they are flexible enough to bend when waved (that is, they flop around).

I should put a 5.25" drive in my old computer and see if there are any DOS games I want from the old floppy floppies.

Circa 1990:
Person A: "Can I borrow a floppy disk?"
Person B: "Hard floppy or floppy floppy?"

pencil you in

To tentatively make an appointment or commitment. Implies it could be changed or canceled, since pencil marks are erasable.

Bob: "I got tickets to Saturday's game. You want to go?"
Tom: "If I can. I might have to work that day, but I'll pencil you in."

percent

Amount per hundred. A concept which many people are somewhat naive about. Often abbreviated as "%" (the percent sign).

I've read that people will often treat a 0.1 percent chance as less than a 1-in-1000 chance, even though they are exactly the same amount. *shrug*
