Mother Everyone's Fucked. Derived from the example of MILF as noted in the classic movie, "American Pie". This term is used for a female who use to be a slut, but then settles down, gets married and has a kid.
"Damn, I ran into Jen today and found out that she's married and had a baby. You remember Jen don't you?? What a MEF!"
