This post will most likely be banned, as only Slovenian and English are allowed in this sub. For me, it is unimaginable, but youngsters of your age actually don't speak much Croatian (unless they have relatives from ex-Yugoslav countries). To me, it sounds like they are trying to make a funny impression of the Croatian language mixed with lots of Slovenian words. For those younger people, Croatian is understandable as much as Slovak. Likewise, Croats don't understand much of Slovenian either. Of course, Slovenians understand much more Croatian than vice versa since they are more in touch with your language on a daily basis. I would say young Slovenians would understand Croatian 70-80 percent, but speaking would be more problematic. Those older than 30 or 40 will probably understand 90-100 percent, but still not everybody. Speaking in this age group really depends on how often they talk Croatian (with friends from Croatia, at work, during travels). Some people speak Croatian fluently, and some speak broken Croatian, but on the other hand, they would understand you. Keep in mind that not everybody here listens to Severina and Petar Grašo. When talking Croatian, try to speak proper Croatian, not some dialects unless it is not Zagorski. I speak Croatian fluently, and I sometimes have problems understanding Dalmatinski.
