Most people are familiar with certain texting codes and abbreviations, such as "lol," "brb" or "ty."

Some codes that being used by teenagers in text messages and on social media sites, however, are causing alarm among parents.

"The Cyber Guy," Kurt Knutsson, joined Anna Kooiman on "Fox and Friends Weekend" to help crack some of these codes.

"There are ones that you want to keep your eye on, that absolutely don't belong in the house at all, period, and don't belong in, especially, real little ones' lives," Knutsson said.

He added it all depends on the age of the child, and it's up to parents to use their best judgment.

To help parents, Knutsson shared some texting translations that many might not be familiar with.

"Code 9" means parents are around.

"NAZ" is asking for name, address and ZIP code.

"1174" means you are invited to a wild party.

"LMIRL" translates to let's meet in real life.

"RU/18" is asking if you are over 18.

"More than anything, this is a reminder to bring together the technology that your kids are using into the family, so we're using it in common areas," Knutsson said. "And also, if they're signing on to social networks, mom and dad should be signing on also."
