MILF

Acronym for Mom I'd Like to Fuck
We all know this. It was originally used by teenaged boys to refer to the mothers of other teenagers. Can be used to refer to any woman around the age range of your own mother whom you find so attractive that you want to have sex with them.
BUT- should NOT be used to refer to young mothers with babies. OF COURSE young fertile women are attractive to men. That's a basic human reproductive instinct. Or in other words, it's just coveting your neighbor's wife. The idea is not that they have born children, it is that they are old enough to be your mother

Guy 1: Is that your mom?! Damn, dude, she's a total MILF!
Guy 2: Don't even talk about my mom like that!
