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 day spent smoking marijuana.
Saturday was a green day.

A sort-of punk rock band that was good but not extremely popular until recently, when thousands of teenyboppers found out about them on TRL, believing their newest and worst CD to date to be "teh bset". Now every fourteen year old in the country rants about how great Boulevard of Broken Dreams is and are known to exclaim things such as "OMG BILLY JOE IS HAWT!!!1" and "DONT WANNA BE AN AMERICAN IDIOT!!12". Their new CD is mediocre at best, so please listen to their other albums instead.
The typical Green Day "fan" has never heard of Nimrod or Kerplunk, but totally eats up the new pop-punk garbage.

1. A day which is mainly spent smoking the drug marijuana, in an effort to end boredom. May have originated in California in the mid-80's.

2. A popular punk rock band with members from Rodeo and Willits, California.
1. I had a green day yesterday.

2. Mike Dirnt and Tre Cool are also members of Green Day.

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*

1) A day to smoke weed.

2) Popular American pop-punk band with such classics as Good Riddance (Time of Your Life), Basket Case and Longview. Sometimes said to be inspiration for various later pop-punk bands.
1) It was a green day.
2) I am going to the Green Day concert next week.

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!"
