Origin of baby-mama

African American Vernacular English (General American would be baby's mama), 1990s, popularized 2000s. Possibly from or influenced by same term in Jamaican English, from Jamaican Creole baby-mother (“pregnant woman”) (1966), alternatively due simply to grammatical similarities between AAVE and Jamaican Creole.
