If you know a teenager or young adult then you have probably watched them text away almost nonstop.
Often the code is difficult to crack and can reveal more than you think. To parents, it just looks like jumbled letters.
So we did some detective work and found some of the most popular codes are actually sexually explicit.
When it comes to text messaging and their kids, we wanted to know how up-to-speed parents are with text "lingo."
More specifically, could they de-code sexually-charged one-liners that researchers say are becoming more and more popular.
If you don't have a clue what "GYPO" means, don't feel bad. Most parents we showed five sexting codes to had no idea what they meant.
Researchers at the Education Development Center in Massachusetts say sexting is only growing in popularity. In fact, 13 percent of high schoolers were found to have received sexually-explicit messages—many of them "coded" so that adults can't make them out.
Here are a few:
GYPO: "Get your pants off"
IWSN for "I want sex now"
GNOC for "Get naked on camera"
CU46: "See you for sex"
GNRN: "Get naked right now"
Researchers who gathered the sexting acronyms also point to parents, saying up-front discussions need to be had with teens to help them understand the repercussions.
If explicit text messaging includes explicit pictures or video, it could carry real legal consequences.
"It will be child pornography," said Merlyn Horton with the Safe Online Outreach Society. "If they email it to their boyfriend, they've distributed child pornography. So the consequences for these actions is much more drastic than it ever was for mooning or flashing trucks."
