"SEX-ACT" WRISTBANDS.

The thin, brightly-coloured snagbands have been popular in previous years but appear to have made a comeback and caused a controversy through their link to sexual activity. Under the rules of the game if a band is snapped off the wrist of the wearer, the wearer must offer the physical act denoted by the colour. One Facebook group called '**** bands' has 62,041 members and lists meanings of every colour.

One eight-year-old explained to her mother: “If they snap, I have to make a baby with a boy.”

When a mother questioned her ten-year-old son about the bands he said: “If I snap a black one, the girl has to ‘do sex’ with me.”

Matthew Tomlinson, who is also chairman of the board of governors at Leyland Methodist Junior School, said: "The head teacher has been working hard on this issue. "

"He's visited the shop in Leyland that's selling these bands and has asked them to take them off sale and there will be a message in the school newsletter saying to parents that these bands are not permitted at school."

Schools do not allow/banned the bands as they go against school uniform rules, but there are also concerns about the sexual messages they convey.
