fmf day

FMF Day stands for Fuck My Friend Day.
While hanging out in the backyard, all of us friends declared it FMF Day. We went inside and fucked in a pile.

FMF

Fuck me forever

When you know it's over with someone, and though the regret you feel tears you apart, this lets them know how you want them to feel about you. Not because you feel the same about them, but there's nothing more you can do.
I can see this is going nowhere. You still have no idea how I feel, but it doesn't matter now. You'd best forget about me... FMF.

FMF

FMF can also refer to "fill me full". As in group sex or orgy. When I mentioned it to a female friend she said to her it ment fuck me forever.
I learned this off Craigslist. A female had FMF DP. As in fill me full double penetration.
