We didn't call the decade the "10S" when we were living through it

[John]

I notice that the years 2010 to 2019 are referred to widely now as the 10s, The BBC have recently launched a Sounds of the 10s hour on Radio 1 for example. Living through it though, it was completely nameless

And the decade before it is known as the noughty noughties

[John]

To be fair, the noughties had become common before the end of that decade, I remember using it in 2003, although it was the first time the people I was talking to had heard it

Tens seems to be a problematic term, I've never heard anyone call the 1910s the tens either but it's normal to say the twenties, thirties, forties etc.

I heard them called teens and teenies a few times.

I heard the term 'the one ohs'.
