The term "Gypsy" is often used to refer to the Roma/Romany people, an ethnic group with a history of nomadic travel and distinct cultural traditions. In Hawaii, the term "Gypsy" might be used to refer to someone who travels a lot, but it wouldn't be a specific cultural designation.
It's important to note that the term "Gypsy" can be considered offensive and outdated, as it has been used in ways that perpetuate harmful stereotypes.
If you're looking for a Hawaiian word for a person who travels, you could use "huakaʻi" (traveler) or "holoholo" (to roam, wander).
