A woman who, upon being married, takes on the responsibilities of mother for her husband. She will allow him to be slovenly and not have a job, just as long as he remains in the house. If the husband leaves the house, the New Mommy will call repeatedly to check on him and make sure he knows when he's expected home; to the point of where it makes the husband and his friends uncomfortable. If the husband has friends over, she becomes irate and antisocial to the point where the friends are no longer comfortable staying.
Ultimately, she achieves an unhealthy, but very effective control over her "husband."

Dunno, he'll have to check with his New Mommy.
