I don't think it has anything to do with where you live, it's going to be more about who you are as a person and whether you've picked up annoying habits from being influenced by the deluge of American shows on TV, the internet and so on.

I've lived in Oxfordshire all my life and do hear it occasionally by younger people when they're talking amongst their friends. It's not something that can really be generalised though.
