People who say they are Green Day's greatest fans but have only ever heard their 'American Idiot' album. They dye their hair black and wear eyeliner like the lead singer. And then they buy converses and class themselves as 'punks'. They really and truly suck and have to get a life.

Green Day Trendy 2: "I've only heard one of Green Day's songs...ah well, I'm still their biggest EVER fan coz I wear a hoodie with their name on!!!!!!1!11!"
