As someone who needs to take dopamine five times a day just to have my body and brain act something close to normal, I've learned to completely tune out people's memetic overuse of the word. I take it to mean just a hand-waving reference to brain chemistry. In my case, it feels to me that dopamine is closely related to various feedback systems that the human brain and body use to modulate and control everything from limb movement to attention to blood pressure.
