I moved a lot growing up (I went to ~10 schools before finishing high school). Picking up local expressions is totally a thing that happens without you even realizing it. The other part of that is that I often would say things after a move and get confused expressions because I didn’t know that something was just a local expression from a previous home and wasn’t widely known. When I was younger, I used to pick up the local accent as well if there was one. However, I have found that I don’t pick up the accents as much these days as an adult.
Having lived for a while in Phoenix, Arizona, I can also confirm that malls serve as a gathering place in very hot climates. At least, pre-internet, my friends and I at the time would usually end up hanging at the mall or the community pool. It was way too hot outside to do anything else really.
