The socially-acceptable acronym for a game teenagers play called Marry-Fuck-Kill. When given a choice of three names, the players must decide who they would prefer to marry, fuck or kill.
Player A: For this round of MFK, we'll go with Cameron Diaz, Angelina Jolie, Lindsey Lohan

Player B: I'll marry Cameron because she's funny, fuck Angelina because she'd be crazy in bed, and kill Lindsey because she sucks at life.

Player C: Kill Angelina because she's crazy. Marry Lindsey because she's going to make lots of money. Fuck Cameron because she's hot.

A game, usually played by girls. It stands for Truth, Dare, or Marry-Fuck-Kill. Player 1 will ask, often by writing it down, if Player 2 wants T, D, or MFK. Player 2 chooses, and if it's Truth or Dare, a question is asked, or Player 2 is dared to do something. If MFK is chosen, Player 1 picks 3 people (if it's girls, guys are listed, if it's guys, girls are listed) and Player 2 has to say who they would rather marry, fuck, and kill. Usually the people are people Player 2 doesn't like, but sometimes they could be people they really like. Basically just a game for very bored people, and it's ALWAYS entertaining.
Girl 1: I'm SO bored.

Girl 2: Let's play T, D, or MFK!

Girl 1: Okay! You first. T, D, or MFK?

Girl 2: Ummm...MFK.

Girl 1: Guy 1, Guy 2, and Guy 3.

Girl 2: I hate all of them!!!

Girl 1: *laughs* Just choose.

Girl 2: Fine. *laughs* Kill Guy 2, marry Guy 1, and fuck Guy 3.

*Laughter*

Girl 2: Your turn!

You get the idea.
