A Punk Rock/Pop band from Oakland, California. Started out in 1986 as sweet children and later changed their names into green day. Started releasing music as independant artists and in 1993 signed to a major label to release their hit classic, Dookie, which would go on to sell 15million copies worldwide. After their 1995 album Insomniac, the band would expirment with other genres such as hardcore punk, ballads and folk punk (as seen in Nimrod and Warning). The band's latest album, American Idiot, shows them experimenting with rock operas and more politically driven lyrics, as well as a less distortant, cleaner sound. Their new, political, left wing image caused many older GD fans to critisize them as "sell - outs" when they had been on a major label for over ten years. Sadly, most of their new fans only know them from American Idiot and never heard the old green day, who sounded more like a mixture of the Sex Pistols and The Ramones.

1. a day set aside to smoke grass.

2. a poser punk band from Oakland, California that whines about boredom. The singer sounds like he has a pile of shit in his mouth.
1. Let's have a green day!

2. the best thing you can say about the Green Day CD "Dookie" is that it has some tenth-generation Ramones chords on it.

A pop-punk band that became extremely popular with the release of their third album,'Dookie', which was released in 1994 and sold over 10 million records.Green Day revived their popularity in 2004 with their critically acclaimed album,American Idiot.This album proved controversial with fans because Green day garnered many new fans that never knew who they were until this album was released.Although to this day 'Dookie' still remains the highest selling Green Day album and a favorite of most fans.

Green Day members include Billie Joe Armstrong (Lead singer and guitarist), Frank Wright III (better known as Tre Cool, drummer) and Mike Pritchard (better known as Mike Dirnt, bassist). Many say that Green Day invented pop-punk and have inspired other pop-punk bands to start. Green Day release their first EP (1000 Hours) in 91, but had their first big hit (Dookie) in 94. Hit songs include, Basket Case, Brain Stew, When I Come Around, 409 In Your Coffeemaker, Good Riddance (Time of Your Life) and most recently Wake Me Up When September Ends.
