FFF is an acronym for "Fucked Face Friday". you can use this acronym as a hashtag on a friday if you post a picture of either yourself, a friend or a stranger making a fucked up face.
on Friday, Hannah posted a picture on instagram of Sammie with a dumb look on her face and used the hashtag #FFF
The glow of one's face when they have had an incredible fuck, can sometimes last for days.
She just came back from her lunch break with her FFF, yeah, where did she go?, come to think about it, Jim disappeared too!
weird.
