The word tattoo comes from the Tahitian "tatu" which means "to mark something." It is arguably claimed that tattooing has existed since 12,000 years BC.
Since the 1970s, tattoos have become a mainstream part of global and Western fashion, common among both sexes, to all economic classes, and to age groups from the later teen years to middle age. For many young Americans, the tattoo has taken on a decidedly different meaning than for previous generations. The tattoo has "undergone dramatic redefinition" and has shifted from a form of deviance to an acceptable form of expression.
