What does the black outlined star tattoo on a persons neck mean or did mean before it became the new tribal band?

first of all, "new tribal band"? stars were a mainstay in tattooing long before the typical tribal arm band. and they don't "mean" anything. tattoos mean different things to different people. stop looking for a set standard of meaning in all tattoos/tattoo designs. many tattoos are simply whimsical and fun or aesthetically pleasing. they don't all mean things.
