Police have issued a list of secret slang terms and acronyms used by teenagers on the internet to help parents spot the telltale signs of online grooming and abuse.

The extensive list released by Nottinghamshire Police includes popular terms and hashtags which teens regularly use to communicate online.

The force are warning mum and dads to familiarise themselves with the phrases which could also flag up issues surrounding mental health, sex, and drug usage.

They include warning flags such as CU46, meaning 'See You For Sex', LMIRL which stands for 'Lets Meet In Real Life' and NIFOC - 'Naked in Front of a Computer'.

Hashtags which are deemed cause for concern include #ana for, anorexia #deb for depression and #sue for suicide.

Police released the list of 200 phrases ahead of Safer Internet Day earlier this month.

But children's charity NSPCC has now emphasised the importance of parents keeping up with the latest slang and hashtags to help keep their youngsters safe.

An NSPCC spokesman said: "One of the best ways for parents to keep their children safe online and spot risks is to open up conversations about their online lives.

"It is important for parents to keep up-to-date with the type of content, features and risks, as well as know the minimum age of the sites and games their children are using.

"Particularly, when we know one in four young people have been contacted over social media by an adult they don't know, with a third of these children 13 and under.

"One of the ways we, in partnership with O2, are helping parents keep updated with their children's online lives is through our Net Aware site which reviews the 50 most popular apps, sites and games their children are using."

A Nottinghamshire Police spokesperson added: "It can sometimes seem like teenagers are speaking a different language and, while it's tempting to try and keep them from interacting online, the reality is that it's as much a part of their life as eating their dinner or brushing their teeth.

"Instead, you should make sure you're aware of the risks of some of the main social networking sites and have the relevant conversations with your children.

"It might seem that grooming has become much more prevalent in recent years, but the truth is it's simply become easier.

"Now, it's much easier for someone to get access to multiple vulnerable young people at one time, and the only tool they need is a computer or smartphone.

"This is not supposed to terrify you or your children, but it is important that you familiarise yourself with online safety."
