caffeine obtained from coffee
This morning, I brewed some java to get a coffeine rush.
Coffee that is drunk solely for the purpose of taking in caffeine. It is usually watered down with milk and sugar, and always of poor quality. It is consumed by caffeine addicts because it's a cheap and readily available fix; pleasure has nothing to do with it. Coffeine may taste like burnt poverty and dreams crushed in cubicles, but it'll give you a buzz just as that posh Fair Trade stuff your aunt's always raving about.
Marla slugged down the rest of the coffeine they were serving in styrofoam cups at the morning conference. It was times like these that she really hated herself.
