Green Daying is a verb, which describes when somebody is listening to songs by the American Punk Rock band -
Green Day, continously, for a fairly large amount of time.
The reason verbs like this do not exist for other bands, is because not all bands can be listened to for a
long amount of time, without getting boring.
Usually, iTunes is used to Green dayage. But Sometimes MP3 players etc. can be used. In most cases, at least 15 or more songs are needed to Green Dayage.
A true Green Dayager will try to get his/her hands on every
Green Day song avaliable, through any means possible.
For many
people, Green Dayaging is a hobby. It's something they like to do when they are feeling down, or why they are feeling up, or... in fact, in any mood.
