look up any word, like potate:
 
1.
someone who claims to be a green day fan, but only owns american idiot, and EVEN SO only listens to tracks 1, 3, 4 and 11.(american idiot, holiday, blvd. of broken dreams, and wake me up when sept. ends) also thinks that american idiot was green day's first cd. can not recognize billie without eyeliner, black hair or a tie(and do not know that he is MARRIED). if you are a real green day fan, it is EXTREAMLY difficult to prevent yourself from chewing these people out, screaming at them, or bitch slapping them. you just sit there and you eye twitches.
{acctual converstion between me and my longtime friend}

Teens who tend to like Green Day because of their latest hit CD, American Idiot. Barely listens to other tracks on the album other that 1,3,4, and 11 (American Idiot, Holiday, Boulevard of Broken Dreams and Wake me up when September ends.)
Characteristics (sp?) of Green Day posuers;
- doesn't know Dookie
- doesnt know what E.B.P.M. is
- has no idea what F.O.D. means
- thinks American Idiot is their first album when actually, it is their seventh album (excluding 1039 Smoothed out Slappy Hours, International Superhits! and Shenanigans)
- thinks Green Day has only been around for about the last 4~5 years.

Well, they're some of the characteristics. There's tons more to recognise a Green Day posuer.

It is very hard for us, real Green Day fans to not to scream at them until their ears bleed, slap them and tell them to go listen to Kerplunk.
If you know;
- who wrote 'My adventure with Green Day'
- and what the story is about
- what was the first song Billie Joe wrote, and what age he was when he wrote the song
- the three main members' current marital status, and their children
then at least I know that you know a bit more facts then those Green Day posuers.
