Things that I think are very Punk Academia:
Being ahead on your studies so that you can watch movies in the back of class on Fridays
Having very strong opinions on EVERYTHING
Not bringing a pencil to school and instead only bringing lead refills and using the ones you find in the hall
Annotating political theory with stuff like "Real shit" and "What the fuck"
Sneaking your friends copies of books that they aren't allowed to read
Tons of candy sprawled throughout your bag, gummy bear packets in every corner
Baking treats and bringing them into your class without any further notice
When questioned on this, you simply say "It's my birthday" which doesn't work as well the 6th time you pull it
Writing your initials on EVERYTHING
Whenever you're given a topic, you search for hours to find common misconceptions you can bring up during next days discussion
Buying everything in cash
Listening to non-western classical music
Realizing how bigotry can be baked into seemingly harmless statements
Likewise, calling people out for their shit when they say these things
Buying electronics second hand
Big off-brand headphones that are a size too big
Sewing patches onto your clothes in the middle of class
Conversely, fragrances that are the complete opposite of that expected for your gender
Seemingly a slacker but having the highest grades of anyone in your class
In many bands, none of which sound like the others
