Tongue piercing has been a growing trend amongst young people since the 1980s. Its popularity has grown along with other body piercings in unusual places like eyebrows, nostrils, lips, navels, nipples, and elsewhere. It’s considered a form of body art and is no longer reserved for those considered rebels or freaks, but can be found in men and women of all social classes.
There is some history to the act of tongue piercing, though it’s not done now for the same reasons it was back then. In the days of the Aztec and Mayan civilizations, tongue piercing was part of their religious and performance rituals, though the piercing was not used to hold jewelry or kept open on a permanent basis. It was meant as a sacrificial offering to their gods.
The practice was not really seen again until the early 20th century when carnival workers used tongue piercings as part of their attraction to side shows.
It’s unclear why body piercings became trendy in the last couple decades. Women I’ve talked to told me they got their tongue pierced because they thought it looked cool, or because it was something different that made them stand out from other women, and a couple even confessed to doing it so their men would have a better experience when she performed fellatio.
