Reply #91: It carries connotations that the father is absent in the child's life no matter where it's used.

1) The mother of your child(ren), whom you did not marry and with whom you are not currently involved.

2) A term used to define an unmarried young woman (but can be a woman of any age) who has had a child. As mentioned before in another definition, most of the time it is used for when it was simply a sexual relationship, compared to ex-wife or girlfriend. Usually this has a negative connotation, a lot of baby mamas are seen as desperate, gold digging, emotionally starved, shady women who had a baby out of spite or to keep a man. Sometimes they may act like this because of missed child support payments, unfulfilled promises by the father, or convenient sex by the father. Either or both may exist in any situation.

Extremely disgusting and lame word.
