A modern couple who prefer to enjoy life a bit before having kids. Usually the couple will be seen as "careless" with money - when in fact they're just harmlessly spending the money they have saved by not having kids early in life.

"Double Income No Kids Yuppie"

Seen as derogatory term by over-jealous idiots that decide to have kids at 16 and therefore have lost the majority of their youth to dirty nappies and child benefit.

Little do they realise that most DINKYs settle down at 30 and have kids - so they get the best of both worlds. In fact most DINKYs by this point have been able to save some of their extra cash to support the child when it finally comes...giving the child a better chance at life.
"I see the dinkys next door have bought themselves a new 42" plasma screen tv. Its disgusting I tell ya. They don't know what they're missing."

or

"How can you possibly afford that amazing school for kids??"
"oh simple really, we were DINKYs until about 3 years ago, so we were able to put some money aside as well as enjoying ourselves...we have enough left over to get them into a decent college when they're old enough too"
