The 20s, 30s, 40s, 50s, 60s, 70s, 80s, 90s...

In general speech I call this past decade the 2000's .... "The Two Thousands"

Same here and most everyone I know.

Funny how you heard Nineteen O One, but never Twenty O One (opting for Two Thousand One)

Funny, now that you mention it, I always read 2001: a Space Odyssey as TWENTY-OH-ONE. Seems odd to me as Two-Thousand-oh-one.

The Oughts.

[SlipperyLilSuckers]

The Naughties.

The Naughties.

That was more of the 90s for me , but as a catchy nomenclature, devoid of an alliterative/analogous meaning ( as in, "the naughty nineties", in my case)....it works.
