Teen girls in some countries are getting inked to the side of their faces and being filmed naked as they go about their business in public.
But it is not quite the same as the popular image of bikini-clad teenagers at the beach, as some experts say the images can be offensive.
The National Council for Civil Liberties says that when they do this they are often accompanied by racial and ethnic slurs.
Bikini-clad teens have also been caught filming themselves, posing for photographs and even making jokes about the girls’ bodies, the NCCL says.
They have been filmed in places such as the South Korean and Vietnamese capitals, Singapore and Tokyo.
The NCCOL says they are not the only examples of teenagers filming themselves in public, with many others posting their own videos on YouTube.
The Council says the images may be offensive to some people, but it has been advised against by the NCAI.
In a statement, the Council said the images are not acceptable.
It said that in some parts of the world, young people who take part in these videos are not aware that they are being filmed and are being subjected to racial and religious slurs and images.
It also said that while there is no justification for such behaviour, the photos should not be used to justify the use of force against them.
In India, where the Bollywood-style bikini-shot is common, some of the country’s most popular stars are seen to be in the midst of a public feud.
The country has been hit by a wave of attacks by angry mobs that have left several people dead and injured hundreds.
In recent days, police in Delhi have detained two Indian girls and a boy for allegedly posting racist and derogatory images on social media, including pictures of their own body parts.
