Another term for leftover coffee - especially really good coffee. When you have too much cold coffee to dump out before starting another pot so you nuke it a cup at a time in the microwave. This is different than re-warming a cup you allowed to get cold. Incentives are high if you buy really good coffee and happens most frequently in the morning or late afternoon.
"Okay, there's plenty of nuclear coffee in the pot. It's good stuff and you can microwave it, so don't dump it out and make a new pot. I don't give a rat's ass if you're a coffee snob. it's to good and I paid to much for it to dump out."
