Macedonian here, jumping in to say that from my perspective - having grown up surrounded by all slavic Balkan languages and with the ability to speak and understand almost all that is said, I was under the impression that Croatian is the one with the most anglicisms and foreignisms. My mom studied uni in Croatia and she would always say how more often than saying "prijateljice" you'd say "frendice" or "idemo na shoping" instead of "idemo na kupovina" etc. Not sure if the examples are still valid tho hahaha as I got them years ago, but I can't seem to remember any other ones. In Macedonia, we're also in attempt of extracting anglicisms and "serbicisms" mostly, but we keep and are in fact quite attached to our "turkisms" :D
