To abandon or desert someone in a difficult position. This seemingly slangy modern term dates from the sixteenth century and is believed to come from a French dicing game called lourche, similar to backgammon. To incur a lurch at first meant to be left far behind, a meaning that survived in several other games, including cribbage. By the early seventeenth century, however, the expression had been transferred to any kind of abandonment, and was so used in Richard Tarton’s Jests (1611): “Ile leave him in the lurch and shift for my selves.”
