Σ sigma. Anyone?

From what has been said before, I think Sigma is a subtle variation of Alpha, although I doubt the young users would agree.

I don't think primary school children got this from Excel!

Sigma is used in Excel when you want to add up a column of figures.

There is no-one called sigma in any Harry Potter book.

Thanks. I was getting carried away with all the magic symbols in HP!

Skibidi is a great word.

Apparently, these words are popular with Generation Alpha 😁

I'm one of the Silent Generation myself although I've been called a Baby Boomer as an insult 🤐

So, I've come across Σ in Maths, and I believe it is a letter in the Greek alphabet.
But has anyone been called it in real life? DH accompanied a school trip to the orchestra yesterday, and the boys declared he was "Sigma". I'm guessing it means something like "cool", but I've never heard it down here in the West Country before.
Anyone? Where is it from?

Another new buzz word among young people.

There was a feature on West Country news about new words, what's in and what's out. They went into a school and interviewed staff and pupils.

Slay, sigma and skibidi are apparently the new 'in' words.
Blame Tik Tok.

Do you remember Dog Latin? We used to speak Dog Latin at school, quite rapidly and it perplexed adults or those not in the know!

There was an article recently on words young people use that are not know to older people. I think it is just part of the way our wonderful English language changes and develops- my grandsons know and use some of these words and it drives me nuts but also makes me smile. My own children had their own secret language and would collapse in hysteics when I used words that had a different meaning for them!

It is Greek originally, but I was told not to interfere too much in how these words are used or their derivation.

In other words, leave the kids alone!

Isn't sigma about the "standard deviation" eg. from a hypothesis?

Or it's just a Greek alphabet letter "S" (?).

I know I used it in maths!

Just found this:
The symbol ∑ indicates summation and is used as a shorthand notation for the sum of terms that follow a pattern.

I'll tell him that, it will make his day! Thanks. 😆
I won't mention the nonsense term bit!
Is it used in Harry Potter maybe?

I vaguely remember a business model called Six Sigma appearing in my workplace many years ago, and various colleagues being given various new titles. It didn’t last long!

Sigma is an Internet slang term, especially among young men, referring to a man whose self-assured, dogged individualism is considered a model of status, success, and attractiveness. It can also mean “extremely good,” and is also widely used as a nonsense term and meme online
