It could just be an audience problem. Teenagers have a whole lingo I am not privy to. Does that mean they are wrong? I probably know more words than the average teenager. Does that mean I’m using them wrong? A lack of knowledge from one party or both can lead to miscommunication. That doesn’t automatically mean someone is wrong. I used to use the term POS in the early days of my Internet use. It meant parent over shoulder so that my friends knew why if I was acting differently all of a sudden. My parents thought I was calling them a piece of shit or referencing point of sale. The former was just funny and the latter was a bit silly. They figured they were just missing something, but it didn’t mean they were using POS wrong. They just lacked the knowledge on one use for a different age group.
