Meaning of Wife

Two guys and a girl were sitting at a bar talking about their lives.
The one guy said, "I'm a YUPPIE. You know, Young Urban Professional."
The second guy responded, "I'm a DINK. You know, Double Income No Kids."

They then asked the woman, "What are you?"
She replied: "I'm a WIFE. You know, Wash, Iron, Fuck, Etc."
