"the act of solving mathematical equations while stoned as fuck - interstingly making the whole process of solving quicker and more efficient"
Coming home from a party at 3 in the morning. Stoned. Drunk. Realizing you have a very important assignment due the next day. Sitting at the table staring at the sheet of paper. At first only seeing weird symbols. Suddenly everything comes into place and you start doing your math at supernatural speed. Afterwards dropping on the floor. Blackout. Wake up in the morning from hangover. Swag. Methematics.
