LURCH, noun [This is the same word radically as lurk. The primary sense is to run, start, leap or frisk about, as a man or beast that flies from one tree or other object to another to conceal himself. Hence we see the peculiar applicability of this word in seamen's language.]
In seamen's language, a sudden roll of a ship. A lee-lurch is a sudden roll to the leeward, as when a heavy sea strikes the ship on the weather side.
To leave in the lurch to leave in a difficult situation, or in embarrassment; to leave in a forlorn state or without help.
