Still, if parents come across any acronyms they believe could be problematic, they should talk with their kids about them, said Greer.
Jones, a computer programmer in Allen Park, Michigan, quickly realized the messages weren't from his boss -- they were from his boss' children who were hanging out at the office with their father for the day.
As a joke, they'd gone into their dad's AOL account and sent silly, innocent instant messages to everyone in the office, and none of the adults could understand the shortcuts and slang.
If the answers are no, you're not a teenager who uses alcohol or drugs.
It all began in 2004, when Jones, a software engineer, received some odd instant messages at work, using terms such as "idk" and "lyk." It was all Greek to Jones.
This may seem overbearing, but remember: Looking at what your child says online could keep your child out of a dangerous situation. "If I have to choose between having my child upset with me or having them be victimized, I'm going to chose for them to be upset with me every time." Of course, it doesn't help to read what they write if you can't understand it.
"There's a broad range of terms that even vigilantly monitoring parents may not recognize," says Ernie Allen, president of the National Center for Missing and Exploited Children.
"Some of this stuff is pretty vulgar." After they read through his dictionary, parents appreciate the education, Jones says.
"Parents write me thank you notes all the time, and I occasionally get hate letters from teens," he says.
Idaho Attorney General Lawrence Wasden agrees that parents need to wise up to what their kids are saying to each other online.
His office has made more than 100 presentations about understanding teen online communications.
I was talking to some of the other programmers, and we thought it would be a cool idea to start a website that had translations of the slang that kids use." Jones created in 2005, and as more readers have submitted terms related to drugs and sex, what started out as a fun little lexicon of innocuous shortcuts has become a valuable educational tool for parents to learn about what their children are up to.
