Greenday is actually the definition of the earliest calendar day for appointments. For instance when you book an appointment with your doctor the earliest day available is the Green Day **Green for go**

overrated pop band who get to much radio play and are adored by all. most green day fans include girls who think they are "goth" by wearing all black, and people who think they are punk, but are actually being flat poser by labeling themselves like that. not convinced that they suck? well recently they played in front of their idol ( i think he's in the clash). they left red faced after the guy said "i dont know who they were, and they werent punk"
wanna be punk/goth: omg green day rulz lolololol dookie lolololol im gonna go play green days shitty drum beats/ guitar riffs at home!!!!!!!!1

1. a band that used to be pretty good consisting of 3 kids who were pretty bored. One day they decided that they wern't famous enough, and sold out. They started wearing all black and eyeliner and started hating bush. Becasue that was the cool thing to do. Suddenly, a million 10-12 year old girls started saying billie joe was so hott, even though he is old and has children. Suddenly, Green day got a million new fans, all of which had no knowledge of their previous CDs.
2. A whole day of getting high.
