If you see the letter “X” appear in your child’s online chat conversations then you could be forgiven for interpreting as an innocent sign of affectation such as a kiss. However, the “X” also denotes a secret that is too sensitive to openly discuss when parents are watching. It’s worth taking a second look to see what is going on.

This emoji is often used in online chats when something has been posted or discussed that is NSFL (“not suitable for life”). It’s an adaptation of the more common NSFW, (“not safe for work”) .
