The meaning of island tattoo is the desire to be alone. Because the island is usually separated from the mainland, people who like island tattoos relatively hope to be lonely and enjoy loneliness.
Island tattoo means isolation. However, this isolation should be viewed dialectically, because almost all the islands are deep in the sea and are connected to the continental shelf at the bottom of the sea, so this isolation is also hopeful to be broken.
