A tattoo consisting of three ots in a triangle, usually found on the skin between the thumb and forefinger, is popular amongst various groups. For Hispanic and Asian gangs, the three dots signify mi vida loca ("my crazy life") in Spanish, and tôi không cần gì cả ("I need nothing") in Vietnamese. As a Sureño (gang) symbol, the tattoo is worn between thumb and forefinger because it is believed to be harder to remove. The Sureño gang number is thirteen, using Arabic or Roman numerals, or a combination of both: 13, XIII, or X3. This signifies the 13th letter of the alphabet, the letter M, meaning "La Eme" or "The M"; the Mexican Mafia. ("Three dots") or X3, which is the representation for the number 13 within the Aztec numeral system. This may explain the origins of the tattoo amongst Hispanic gang members. However, along with the pachuco cross, the three dots is also a popular "generic" tattoo among Hispanic teenagers with no gang involvement whatsoever.
