Green day are a punk rock band, originated in California, being going 1988 to present. Billie Joe, Mike Dirnt and Tre Cool are the members. Their roles are front man on guitar and vocals, bass player and back up vocals and drummer respectively.Their name used to be sweet children but they changed it.Albums include Nimrod, Dookie, Kerplunk, American idiot, international super 1039/smoothed out slappy hours.Many people believe that Green day became sell-outs after releasing American idiot. That is not true. Those people are the “old green day” fans, say that its now not cool to like them because lots of people in high school do, but that’s just sad and ignorant because some fans, like me, couldn’t even walk when Dookie(1994) was released.The 1st song I heard was American idiot, I am ashamed to say that was on MTV, but it wasn’t my TV thank god.I thought wow this is a great song, so I downloaded the album and did a bit of research on the band. I downloaded their old stuff to, and its all equally awesome. I am unable to find a reason why that makes me a poser, but all you lot that do, please keep your ignorant comments to yourselves. Also, many people only like them because they see Billie Joe as “sooo hot init”, which is wrong, but I’m not denying that he’s very sexy, but he’s married with two kids! I listen for them for the music, but its totally ok to think Billie is hot. The lyrics are really meaningful, for example, in basket case.. do you have the time, to listen to me whine, about nothing and everything all at once. This is a phase many go through, feeling depressed but wondering what about and whether its everything or nothing, and this songs shows it in a kick ass way.

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*

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.

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!"
