green day 

Green Day is the name of the now band formerly known as Sweet Children, from Rodeo Cali. The members were potheads as teenagers and were watching Sesame Street once, and they said 'green day' at some point on it and they thought it was funny. So, it became slang for day spent smoking marijuana. John Kiftmeyer (aka Al Sobronte, former drummer of Green Day) had a jacket made that had 'green day' written on the back, and eventually they decided to make it their band name. They also have a song called 'Green Day' that is pretty much about the same thing.
Also, the best band in the world, btw.

'at green day yesterday was awwwwwwsome. the teletubbies are so friggin funny!

Green Day 

A shitty band that rips all of their stuff of the Ramones, Beatles, Sex Pistols and Clash. Inspires many emo retards to mutilate themselves.

I do not want to be an American Idiot (slits wrists)

pop-punk rock band from california. i hate green day; but, i have to admit, i like some of their older songs. their new music sucks. i hate politcal music. but the real reason i hate them is because their drummer(tre) said some shit about one of my favorite bands. it seems to me that they think they're better than everyone else(other bands).

A fucking mainstream MTV band that all of the teenyboppers and poseurs love. If the idiots that listen to Green Day and claim to be punk really thought they were punk, they would listen to stuff like The Casualties. Green Day is POP. Not punk. Not pop/"punk". POP, just like almost every other band claiming to be punk that's around these days.

Green Day 

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.

green day 

1.n. A terrible band that helped start the crappy pop-punk movement in the public eye, thus beginning the coup de gras to real punk as we knew it.
2.v. To kill something great.

1. "Boy, this band sucks. I mean, they're not Green Day, but they're pretty bad."
2. "The Roman Empire was, in essence, Green Day'd when Germanic tribes broke through their borders."
