A song by Willow Smith who sings how she's a 21st century girl when she was born in the last year of the 20th century. Anyways her memories probably only come from the 21st century.

The latest Green Day album, which killed the Green Day name. They decided to go from having albums with:
-Deep meaningful lyrics
-Guitar Solos
-Insane Drum Solos
-Songs with many verses and an infrequently repeated chorus
-A Punk Rock Sound

TO:

-Shallow lyrics
-Few to no Guitar solos
-NO DRUM SOLOS
-Songs that repeat the chorus TOO MUCH (Know your enemy repeats the chorus 12 times!)
-A POWER-POP SOUND

In general, they alienated their true fanbase for critical acclaim and popularity. True fans will hate the album, and groupies will like it.
A groupie and true fan are riding in a care, when the single "Do you know your enemy" starts playing on the radio, the first single from 21st century breakdown...

Groupie: Do you know the enemy? Do you know the enemy? Do you know the enemy? OOOhhhhhhooooo....

True GD Fan: SHIT! This is garbage! what the FUCK? Where are the verses about Conformity, Society's Overcaution, Depression, War Volunteers, Insanity, Breakups, Life in general, Assholes you want dead, and Individualistic Ideals?
God. I'm gonna stop listening to Green Day now... I'm pissed that they suck now

Groupie: They're new stuff is awesome. They're old stuff sucks. Go listen to their old stuff if you like that better. You shouldn't care what the band sounds like if you're a fan

True GD Fan: Bullshit! You're a fucking groupie! Not like you're gonna care in 2 weeks!

Groupie: You're wrong. Billie Joe is cute.

True GD Fan: So, you still like that shitty GD album?

Groupie: No, I listen to Fall Out Boy now. GD sucks!

True GD Fan: Dumb skank... Ah well... maybe their next album will be good...

A term that pretty much describes a guy living in the 21st century who is really obsessed with technology. Inspired by the Bad Religion song of the same name released in 1990 (some may think the song predicted the future but all the digital stuff was already going on around the band during the early 90s).
My brother was known for being a 21st century digital boy as he would always be on his phone and game online.

A cell phone, especially one with no service, a low-end model, and/or one with a flip form factor.

Note, however, that this doesn't refer the pocket watches douchey steampunks wear to be cool.
