Among gang members, this (spider web) tattoo was a code, readable by other gangsters in prison and on the outside, showing that the bearer had served serious time in the penitentiary. In some parts of the country the same tattoo meant that the wearer had killed a member of a minority group. In fact, James Burmeister was convicted in 1995 of killing a black couple, an act he committed solely because he wanted to wear the spider web tattoo that was popular among members of the Aryan Brotherhood.
de drie puntjes komen oorspronkelijk van Latino-bendes en betekenen "mi vida loca" (mijn krankzinnige leven). Later werd dit overgenomen door Zuidoost-Aziatische gangs waar het "to o can gica" (ik geef nergens om) betekende. In Cuba betekent het dat je zit wegens brandstichting.
