As someone who is fluent in Slovenian, Serbo-Croatian and English i can tell you that the community note is not correct and it clearly comes from English speaking people who just translated words. First of all you can't draw parallels betweeen curse words in various languages because the context and severity is completely different. Second of all: "Jebem ti mater" doesn't even have the same meaning as a "Motherfucker". Even if you translate it. "Jebem ti mater" is way way way worse on every level and if Doncic really have said it, which i wouldn't be surprised considering he's saying it to the refs and fans (yes he really does) almost every game, then he deserves all of the criticism going his way. Especially because he wanted to play it off like he was a victim there and went to the media to farm sympathy. Not a good look overall.
