A four-dot tattoo on the hand, particularly on the knuckles, is thought to indicate that the wearer has served four years in prison. Three or five-dot tattoos are also connected with criminals and incarceration.
The three-dot tattoo, which stands for “mi vida loca,” or “my crazy life,” is a sign of Latino gang membership. The five-dot tattoo is made up of four dots that create a square, with the fifth dot in the centre. The four walls of a jail cell are depicted in this tattoo, with the single dot in the middle signifying the prisoner. Both of these tattoos are usually seen between the thumb and index fingers on the back of the hand.
