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-

Quality band which poeple tend to see as sell outs because of their last album American idiot. For me they will always be remembered for Insmoniac and dookie two of the best punkish albums I have in my collection. Unfortunatly their main following now consists of teeny boppers who only discovered Green day existed when Boulevard of broken dreams came out and wouldn't know "At the library" from "Westbound sign" Still i suppose they had to find someone to fantasise over after Busted split up. DAMN YOU CHARLIE!!
girl 1: "wow have you heard that new band Green day?"
girl 2: "Yeah, billie joe is gorgeous"
me: "For gods sake! they have been around for 15 odd years!"
girl 3: "really? wow do you reckon Nirvana will ever get back together? that would be qualtiy"
me: *sound of me crying on the floor in utter despair*

A band that started out as "Sweet Children" playing at gilmmans street,
on the "lookout records" label, eventually they became biggewer and had to switch labels becuase of the over demand of Kerplunk, became very big once dookkie came out. relesed a few more albums. they were called sell outs for leaving the underground and lost much of there fan base, with thier aucostic song "good radiance", even more now with thier release of thier new album "american idiot" which blew up more than dookie, getting into the mainstream more than before with American idiot", "holiday" , "bulovard of broken dreams" and recently not as much play "wake me up when september ends", causeing many things.

leading me to this conclusion:
people who think Green day is gay period,
people who think greenday isn't punk anymore and that they are sellouts,
little 10 year old girls who drool over billie joe and don't know shit about them ,
the adults that really don't give a shit,
and the true fans who love all thier music even if it's punk or not

thank your for reading, and have a good day.
Haters: greenday is gay
Older fans: F**king sell outs
mindes girls: i love greenday for noreason
adults:........what?
true fans: you people are really screwed up

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"
