Yes. Almost always.
As a kid, we wanted to obscure what we said from the adults or at least make them stop listening (there was a phase when I was in school of including a speech impediment when speaking; we found that teachers didn’t listen to us after a little while.).
We’d either done something the adults had forbidden or were about to, something that would cause us embarrassment if the adults knew, or it was just more exciting if they didn’t know.
As the adults catch on to what things mean, we all using those terms in that specific way.
I’m using ‘adults’ to mean someone who is responsible for themselves so somewhere between eighteen and thirty.
If you’re an adult reading this in the UK and US (maybe other places), urban dictionary is your friend.
As does aural frequency range. There are some anti teen alarms which use high pitched sounds only teens can hear.
