Things have changed for a word that despite being around in written text for 900+ years, didn’t even get listed in the Oxford English Dictionary until 1972.

NICOLE HOLLIDAY: I never say this word.

HZ: No, I feel bad to force you.

NICOLE HOLLIDAY: No, it's funny. Well, I'll say it on podcast, this is professional environment; but in my normal daily life, I can't imagine that I would personally say it. And this might just be like, I'm kind of a prude and I was raised kind of religious, but it does sort of seem like beyond the pale for me personally. I wonder if were 20 if I wouldn’t feel that way, but I spent so much of my life like judiciously avoiding very strong taboos. And this one, just my gut reaction is that it overwhelms. So when you asked me to do this, I was like, “Oh, no! I have to say that word!”

HZ: I'm sorry. We could probably skirt around it and then people can spend the whole episode trying to guess which word we're talking about.

HRISHIKESH HIRWAY: Did you know that, Samin, that my nickname for Helen is 'Pizza’?
SAMIN NOSRAT: What? Because of all the Z's?
HRISHIKESH HIRWAY: Because I once told Helen about this atrocious pamphlet that I read at the train station when I was in college. It was for some kind of like - I think it was called student advantage. Do you remember the student advantage card? There was a pamphlet for student advantage card, and they were trying to say like how useful it could be. And they're like, "Everybody knows students need a few extra bucks, whether it's to do laundry, buy some books, or just grab a slice of 'za!" And I had never heard that before, 'za, apostrophe Z A, and I was looking and I was like, "Are they trying to say pizza? They're abbreviating pizza? This is how cool kids say pizza. What is this?" And I felt so offended that they were trying to market, at me, a student, using this kind of language. And I told Helen about this, and then immediately after that she was doing a Reddit AMA and, and I think I went in there and I asked her if she was really hiding the fact that Helen Zaltzman was short for Helen Pizzaltzman.
HZ: Yes, my family shortened it when they moved to an Anglophone country.
HRISHIKESH HIRWAY: Yeah, so now I just call her 'Pizza' for short. Naturally.
HZ: I just think an abbreviation where you understand less what the thing was is not a good one. I suppose you are saving a whole syllable which is half of the effort.
HRISHIKESH HIRWAY: Plus you sound SO cool and SO with it, calling it just 'za.
HZ: And you must be very busy person not to be able to do the full 'pizza'.
HRISHIKESH HIRWAY: You're a student, you've got skateboarding to do.
