21st base

Giving yourself a blow job. Then your penis blows up. And then the world blows up. And a penis takes its place.

Friend Isn't that just 20th base but extreme?

Me:Fuck yeah it is. 21st base is better though.

21st century

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?"
