What is definition of milf?

A "milf" is an acronym for "mother I'd like to f***". It is a term used to describe an older woman, usually a mother, who is considered sexually attractive and desirable. The term originated in the 1999 movie, "American Pie," and has since been popularized in mainstream culture through pornography and various media outlets. While the term is considered by some to be objectifying and derogatory, others embrace it as a compliment and a celebration of the sexual attractiveness of mature women.
