1.A day wasted by being wasted

2.a punk-rock-pop band assembled of extremely talented musicians who are filthy rich, no wonder. Tre Cool; drummer (2nd main drummer of green day), Mike Dirnt; bassist and vocals, Billie Joe; guitarist and lead singer. Their old look was so much better than their new mod-suits of the dead, but whether the new music is better than the old is a personal opinion.
1.My cousin died from having a green day, hope you're happy!

2. How can you say green day kills?

Green day is a "band" that went on tour to unseat the United States President George W. Bush. i am not a fan of communism. they also suck. Phish is real music
fuck bruce springsteen, john fogerty, green day, John mellencamp and neil young (the other communists that went on the vote for change tour)

I had a lot of respect for green day until the came out with american idiot. Which means they sold out and started to do the waaaaa our life sucks emo shit. But I still give a lot of credit to them for every album before american idiot.
the sadest thing about green day is there is actually 4 people in there they barely ever show the 4th guy but he does all the solo's. at least on the new album.
