DIOK
Dual Income One Kid. An extension of DINK. This couple has far more disposable income than Multi-child families, but not as much as DINKs.
Chris and Shelly just bought a new car. Must be nice to be DIOKs.

Double income, one kid. A household with 2 adult wage-earners and one kid.
Bro, life was so rad before me and Kate mixed up the babybatter. Now we're dioks and have zero disposable income. Babies are financial leaches.
