Interesting! Teenager girls i.e. those between 14-18, have a very distinct language here too. For example, they use a lot of "like" and "kind of" in thirr sentenses withought any need. For example:

Normal: I saw John when I was going there.

teenage girl: I was like going there that, oh my Gosh, like saw Johnny!!

This language continues to the early years in college too

Saying a lot of "Ummm" and speaking with no certainity is popular among young girls in English so that's probably where the Iranian version comes from.

Another common problem here is "uptalk" - the way kids speak so that every sentence ends with an interrogative tone so that it sounds like a question even when it's a statement? Like that, in fact!

Language experts think that "up-talk" is associated with other features of west coast (i.e California) "mallspeak", such as the girls habit of self-interrupting sentences with "like", using the intensifier "totally", and responding to any actual question (as opposed to an uptalk interrogative) with "whatever".

Example:

"So what did you do today?"

"Well, we went canoeing on the lake? Which was, like, really really fun? And then we had storytelling in the barn? And we all had to tell a story about, like, where we're from or our family or something?"
