This is not an official language of lao, So I assume they can use it just for their own group or gang but I don't think can use it in the official form like in School, workplace, or in the government facility...
It is called Lao kids are developing a bad habit of speaking improper Lao language ( their own mother tongue language!)STUPID!!!!
STOP MAKING EXCUSES FOR YOUR OWN STUPIDITY, KID!!!!
