Google finds no evidence of the phrase milf at eleven anywhere on the internet at the moment. Which isn’t necessarily weird, since it’s a silly phrase, but it seems like it should be documented.

On the other hand: Eleven killed in MILF attack in Maguindanao.

[Hat tip to mefite Debaser626 for either inspiring me with related weirdness or actually scoring the coinage but for a typo. It's hard to be sure which is the case.]
