FMK is an acronym used for F*ck, Marry, Kill.
It's a game that's been played for decades, popular mainly amongst teen and young adults and in party
situations.
It's used mainly to decide, among 3 options which one is the best, fuck for a one time only thing, marry for the best one, and kill, yeah, to kill.
On the meantime, it has also become an app called playfmk, where you vote and play with
real people. And if two people vote the same for each other, they even get to text each other.
