Shag, Marry, Cliff (known alternatively as: Fuck, Marry, Kill, among other names) is a sort of party or road-trip game. One person gives three names, and the next person says which of the three they'd screw (or shag or fuck, whatever), marry, and throw off a cliff (or punch or kill, whatever). It can continue on or the "players" can sit and discuss their terrible life choices.

1) Comment with your character.
2) Reply (ICly) to others with three names to choose from.
3) Say who you would shag, who you would marry and who you would kill/cliff.
