look up any word, like sapiosexual:
a MIF is a MILF without the L.
In other words, a mom that I fucked.

Similar to MILF "Mum I'd Like To Fuck", however MIF stands for "Mum I Fucked".

Ryan: Kenny your Mum's a MIF

Represents a description of woman, most likely the mother of a close friend, in a given point of time. MIFs are women who used to be known as MILFS. Mother I Fucked!
1.I enjoyed her transition from a MILF to a MIF very much.

2. Dude, did your mom tell you she aint a MILF any more?

3. Steve, I finally did Maja. - Whoww.. so she turned from a MILF into a MIF.

Mom I'd fuck. Precursor, and more concise form of, the term MILF that was around long before the movie American Pie
Even though matt's mom is sixty, she is still a MIF
