Acronym for Mother I'd Like to Fuck. Although the following is debatable, a MILF refers to women in their late 30's through mid/late 50's. She doesn't necessarily have to be a mother. For example, a hot 16 year old mother doesn't qualify to be a MILF; whereas, a 45 year old hot babe who is not a mother would. Same would apply to GILF.
"Awww yeaz! check out that MILF!!"
"Yah, she's aight but I don't see no stretch marks tho."
"C-Section nigga..."
"Aight bitch, imma gonna ask dat ho if she's got children. Then you gonna pay me $5 cuz you'z ass is wrong."

"Awwww yea check out those saggin tittaas, definitely Grade-A GILF material right there."
"Shiiit, thats the old spinster who lives up on Cherry Rd... she never married or had children foo, you'z be trippin. Ain't no GILF in that, whats the fun if she ain't got no kids foo?"

"Mother I'd Like (to) Fuck"
mothers, whether married, separated or divorced, that a male individual sees as physical attractive enough to want to have sexual intercourse with them. Just cuz their moms doesn't mean that they don't need a spark in their love life. If they've ever breastfed,they have really responsive nipples and a core of erectile tissue in their breasts. The ones in good shape have worked at regaining control over their vaginas (Kegel exercises).MILFs are usually real careful about birth control, they know accidents happen but they take responsible steps. They want to fuck with abandon, with no romantic complications for their under-19 family.
A MILF is any mother that is sexually desirable.
