Green Daying is a verb, which describes when somebody is listening to songs by the American Punk Rock band - Green Day, continously, for a fairly large amount of time.

The reason verbs like this do not exist for other bands, is because not all bands can be listened to for a long amount of time, without getting boring.

Usually, iTunes is used to Green dayage. But Sometimes MP3 players etc. can be used. In most cases, at least 15 or more songs are needed to Green Dayage.

A true Green Dayager will try to get his/her hands on every Green Day song avaliable, through any means possible.

For many people, Green Dayaging is a hobby. It's something they like to do when they are feeling down, or why they are feeling up, or... in fact, in any mood.
Mike had been Green Dayaging all night long and he only stopped because he had to go out. This is an example of "Green Daying"

Get the Green Daying neck gaiter and mug.
The correct spelling of the band. It is not "Greenday", nor is it "gREeN dAY!!11!1!!!".
"When I saw the Green Day concert, Billie Joe was masturbating on stage."

A punk rock band that has been around since 1988. All three members are from California. Green Day consists of Billie Joe Armstrong (guitar), Mike Dirnt (bass), and Tre Cool (drums).

They have 9 albums to date. Their most recent one is American Idiot which is an amazing album (and is also why many people THINK they are sellouts, but they are NOT). But their first big hit was Dookie which came out in 1994.

Even though many people discovered Green Day because of American Idiot, it doesn't mean they're posers. Many fans were young when Green Day's first albums came out and after American Idiot, went out and bought all they're earlier albums and realized that those albums are even better than American Idiot.

People who think Green Day are sellouts shouldn't. And if they do, they should keep their negative comments to themselves.
1. After she heard American Idiot, she went out and bought all Green Day's other albums and realized that they were even better than American Idiot!

2. Without question the greatest punk rock band on EARTH!

1. A day spent smoking weed, usually out of boredom.
2. A pop-punk band formed in 1988, with many good songs out like "When I come around", "Time of Your Life", "Why do you want him?" and more. I discovered them in 5th grade when hearing Boulevard of Broken Dreams on the radio. I looked them up and, well, fell in love with their old stuff as well as new (but preferring pre-American Idiot). But then, I discovered something in 6th grade called real punk. I really got into The Stooges, The Ramones, The Clash, Misfits, Sex Pistols, etc. A year later, I listened to American Idiot for the first time in years and came to a conclusion: that (new) Green Day, while being pseudo-punk and somewhat annoying, is a pretty unique band. Compare them to the other stuff that's out today!

HOWEVER, Green Day started an epidemic of a new breed of poser. It's when someone aged 8-13 believes they are "seeeeew punk rawk" when they listen to Green Day, Blink 182, or Avril Lavigne. They oftentimes don't even know who the bands I mentioned previously are. Those who like Green Day are often seen bashing Bush without even knowing if or even why he is a bad president. Now, not everyone who listens to said music is this way, just a vast majority. Not saying bad things about everyone who likes Green Day, just those who listen to them only and try to be something they're not. To conclude, a decent band.
1. Jimmy's so baked. It's definitely a Green Day...
2. Actual conversation:
Poser in my class: I just love Green Day omg!
Me: Do you listen to anything else??
Poser: Well my favorite artist is Avril Lavigne. It's just pure punk rock!
Me: Dude, thats not punk. Have you even heard of the Ramones? The Clash? The Sex Pistols?
Poser: Well, I havent heard of the Sex Pistols or the Clash. But the Ramones are gay!
Me: -rams head into wall repeatedly-
