Answer: What is Kiss, Marry, Kill mean?

Fuck, Marry, Kill, also known as Kiss, Marry, Kill, as Bang, Marry, Kill, or as Bang, Smash, Dash, or with other synonyms or arrangements of the terms, is a social forced choice question and answer game. As one source describes it, "[w]e have heard of the game "Kiss, Marry, Kill" in which people fantasize about which of the three choices they would exercise on someone". In the game, one person poses three names of people known to the other, typically either names of people known in their personal lives, or names of celebrities. The other person then has to decide which of the three they would have sexual intercourse with (or kiss), which one they would marry, and which one they would kill.
