A police force has shared a 'sexting' dictionary to help parents identify the secret code words their children are using to exchange explicit messages and photographs.

Do you know what IWSN, NIFOC, TDTM or FYEO mean? These are just among the worrying acronyms that are included in the 'sexting code' shared by Humberside Police in response to a growing number of children and teens involved in lewd digital activities. These acronyms actually mean 'I Want Sex Now,' 'Nude Infront Computer', 'Talk Dirty To Me', and 'For Your Eyes Only.'

"We have recently had numerous reports of young people sharing sexual, naked or semi-naked images of themselves, also known as sexting. Therefore, we're urging parents to talk to their children about the dangers of sexting as it could lead to embarrassment, blackmail or even a criminal record," the Police force said in a statement.

According to the Humberside Police, the list also includes codes to alert their sexting partners of the presence of the parents with codes such as PAW, POS, P999. They are acronyms which stand for 'Parents Are Watching', 'Parents Over Shoulder', and 'Parent Alert'.

What is more worrisome is that the list also have codes designed to arrange real life meetings between strangers such as RU/18 (Are you over 18), LMIR (Let's Meet in Real Life), and MIRL (Meet In Real Life)

A similar secret code list was also shared by Northern Irish Police last year.
