A casual way to say a cup of coffee, usually the no-fuss, diner-mug kind that keeps your eyes open and your mood just about civil. It’s old-school American slang, super common in films, offices, and anywhere with a dodgy drip machine. The “Joe” origin’s debated, but the meaning’s crystal clear.
"Grab me a cup of joe from that sketchy break-room pot, yeah? If it strips paint off the walls, it’s officially strong enough for Monday"
