"i need to build up my indie cred"
Indie kid 2: I saw them like five months ago, around the time I saw the Islands.
Indie kid: Next week I should be getting those +/- tickets I ordered.
Indie kid 2: Ahhh I'm so jealous!
And assuming people heard you, you might get more indie cred, and other indie kids think you're cooler.
Dude 2: "Wow that's some serious Indiecred right there."
Though indie cred works both ways, you can also have indie cred taken off you; this usually occurs if the name of a certain indie thing is unknown, such as a band, or fashion trend. In this occurrence the indie man take something indie off you, as you are not deserving of it because you're not nearly indie enough.
"You don't know who *insert band name* are? Careful the indie cred man will come and cut the points off your shoes"
