The years from 2000 to 2999. The 21st century is often used to express how up to date people believe they are or something is.
Example 1: "I only listen to music from the 21st century - none of that old school crap."
Example 2: "I'm a 21st century teen. How do you expect me to relate to old people?"
A crappy era where people only do anything for money. Presidents kill other countries for their things because they don't wanna share with them. Rappers constanly rap about money and women they don't really have and longer for the love of the game. Everything is big buisness and no longer for the fun of it.
Examples of 21st Century crap:
President Geogre W. Bush
50 Cent and Gunit
"The Cookout" and........."Soul Plane"
21st century is an exact replica of the middle ages where only money, glory, sex, fun, celebrity, and power counts.
Guy 1: Ay, What the f*ck is this 21st century?
Guy 2: Come on Bob, lets buy a time machine.
Just another repeat of the 20th Century, but with more focus on globalization, the internet, climate change, alternative energy, (20th Century junk too) blah blah blah that crap along with the constant worry about some Biblical thug will cause some modern day Crusade and get another alliance with another 20th Century thing...Russia. And communism is spreading and you are not even knowing about it, and Muslim religion and Buddhism. History repeats itself. We still got Nukes, moral values and teaching are on the rise, mass communication, media, and they are still agriculure people aka as rednecks.
21st Century = 20th Century. 19th Century was way more cooler and original. Most kickass wars ever.
The century starting in 2001 and will end on December 31, 3000.
You thought the 21st century started in 2000. NO, it was the 20th century still. 2001 was when it started.
