Latcho Drom is an ancient expression in the Gypsy language that means "Bon Voyage", "Safe Journey". It's been used as an expression of good wishes by this migrant people.
When a Gypsy family would leave from one location, in route to another, in search of a better living, those staying behind would simply say Latcho Drom, "have a safe journey" as they instinctively knew the risks and perils that family would encounter. It was a time when an entire family's possessions would barely fill a wooden caravan drawn by a horse or a mule.
