Punk Academia, in my opinion.
Studying either at home with music blasting or at the public library, very quietly.
Possibly drinking a pepsi or something, whatever you got from a vending machine.
Whatcha reading? Books on anarchy, or maybe history, political movements, social studies -- anything that opens your horizons and educates you.
Hell, maybe you're even studying the history of punk rock? Getting familiar with its core philosophies?
Or, you know, you could also be reading a fiction book or a zine.
Taking notes on your notebook with a pencil.
The notebook is filled with poems and lyrics you've created or you've liked from other places.
Written rambling on whatever you read, something that might go up on your blog, or your zine if you have one.
Doodles, designs and stickers all over that notebook and the notebook cover too.
You're dressed however the fuck you want??? As you should??
Your hair is also however you want, casual, mundane, crazy as fuck, who cares.
Finding ways to help your community and those in need, that seems very punk academia.
Discussing what you learned with others.
Educating people who aren't in your scene, too.
Or, hell, talking to yourself about it while you work on a patch.
