look up any word, like tribbing:
 
22.
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-

Green day ~ day spent to just smoking pot and doing absolutly nothing at all. sitting on the couch, eating food, just not leaving the house at all while you are stoned.
My friends and i got our first paychecks today, and we celebrated by having a green day because my parents were out of town.

1) A most wonderful band in the opinion of many. They actually came from humble-to-hectic roots in California- all children of deadbeat parents, but all musically talented. Their usual music is literally exactly what an unhappy, confused, and possibly disgruntled teen goes through; subject matter ranges from sitting around being piss-drunk or stoned out of your mind to being afraid of love.

Now, sadly, it seems that this music has changed, as well as the Green Day image we all know and love. Since when have they swapped ratty old blazers and jeans for tight black pants and pyramid belts? We miss the old Green Day, even though their new music isn't too shabby.

2) A full 24 hours spent smoking marijuana.
1) Billie Joe Armstrong, Mike Dirnt, and Tre Cool are the 3 members of Green Day. Currently, they also have Jason White- backup guitar, as well as other various musicians who help them play. They're quite rad.

2) God, you're really fuckin' lazy! You've had two green days in the past month. Get a job or something, you sad-ass.

Californian punk rock band. Includes Billie Joe Armstrong, Tre Cool, and Mike Dirnt. They formed together in 88 and released their first album in 1991. They became famous for thei album Dookie in 1994, but really hit hard with their 1997 single Time of your Life from their album Nimrod. Also, the GREATEST BAND EVER!
"Green Day rocks!!"
"Dude, I TOTALLY agree!"

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

A common misspelling of the name of the band Green Day.
It's "Green Day," not "Greenday."

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!

(n) 1. a band that used to be good but was taken over by middle schoolers, 9th grade girls, and fake-ass emo chicks.
2. a day where you smoke weed and drink booze; also called 420
1. Green Day is an example of, well, a Green Day band.
2. Stoner: Wow, look at me, I smoke weed, I'm cool, it's a green day.

Some dude: You mean, like the band.

Stoner: Uh, no...wait, what?

Some dude: Didn't you just mention the band Green Day?

Stoner: Oh, you mean the "I walk this empty street on the boulevard of cocks" guys.

Some dude: Yeah

Stoner: oh

(Stoner pulls out shotgun for no apparent reason and blows dude away, because thats always what happens at the end of these gay dialogue thingys)
