Get a Green day mug for your coworker Jovana.
A very good band that originally smoked themselves retarted then wrote up bad ass meaningful lyrics. Kerplunk and 1,039 kicked everyones ass, and dookie is a classic, insomniac made them cooler, nimrod dido, warning again classic, american idiot teased but didn't put out.
Myself: Hey dude wanna go down to the park and smoke 3 bowls then listen to Green Day, and Dre.

Someone who is badass enough for me to aknowledge: yeah

Get a Green Day mug for your fish Jovana.
A very popular pop-punk band formed in 88 in the Bay area.
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.

The absolut greatest punk-rock band ever to grace the face of this planet. For all of you who think Green Day is dumb...stop watching the T.v> get of your lazy ass and get a job. Oh ya and by the way they don't even care if you don;t like them beacuse they know who they are...they are Green Day..the greatest revolution of this cool thing called music.

Because of serious jealous retards that have an internet connection, they write horrible blows about the hands down greatest band of all time. Because of this true lovers of Green Day and their amazing songs should ignore these dick remarks at all costs. Without Green Day most people wouldn't know what masturbation was..gentlemen..please thank them for all the funs times you've had with no girlfrend ;)
JealousFag: Green Day isn't Reel ROCK Mann, i Mean likee operas are GAYY ya no??
GreenGirl: Go suck urself dry
JealousFag: ok..how do you do that again..
GreenGirl: Listen to longview dumbass

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.
