Tuesday, Feb. 11, is Safer Internet Day, a day to promote safer and more responsible use of online technology and mobile phones. The day aims to raise awareness of emerging online issues that reflect current concerns.
And while most parents know what LOL and TTYL stand for, it turns out there's a lengthy list of other, lesser-known-to-adults acronyms that child predators use to communicate with kids.
For example: do you know GNOC? It stands for Get Naked on Camera.
"Good Morning America" reached out to the experts at the Child Rescue Coalition, an organization that aims to protect all children from sexual exploitation, to find out what parents need to know when it comes to predators and those seemingly harmless acronyms.
The group gave us a list of 30 that should sound the alarms if a parent sees their child using it.
The group's advice: "Make sure to have open conversations with your children about what rules you want to set, and clearly let them know that you will check their phone and all the apps that they use."
