For generations, parents and children have found that they sometimes speak in a little different language.

For example, I classified many things as "cool" in my day. I honestly never heard my father say anything was cool except the house when I left a door open.

Now with texting and all the communication devices, the language gap has gotten completely blown out of proportion.

If you've looked at any teen's communications, you'll see them sprinkled with acronyms and shorthand that make no sense. Those letters and numbers that are a code system.

Some codes are totally harmless. But, on the other hand, some are serious. And if you see them on your kid's gadget, it's time to take action.

Some of these acronym meanings are very direct and a little shocking.

Your kid has something to hide:

CD9: Short for "Code 9," which means parents are around.
KPC: Keeping Parents Clueless
MOS: Mom Over Shoulder
P911: Parent Alert
PAL: Parents Are Listening
PAW: Parents Are Watching
PIR: Parent In Room
POS: Parent Over Shoulder

Your kid shouldn't be involved in this:

143, 459 or ILU: I love you
1174: Invited to a wild party
420: Marijuana
GNOC: Get Naked On Cam
GYPO: Get Your Pants Off
AMEZRU: I Am Easy, Are You?
IWSN: I Want Sex Now
KFY or K4Y: Kiss For You
KOTL: Kiss On The Lips
NIFOC: Nude In Front Of The Computer
RUH: Are You Horny?
TDTM: Talk Dirty To Me
