Ukrainian is getting mentioned again because while some of their "original" words sound fine like "Vitayu-Витаю" and "Znecennya-Знесення". When they directly take words from Russian and modify it in a ukrainian way, it sounds awful, but the language overall sounds ugly and unappealing the longer you listen to it. Still, not as bad as the following ones
Arabic was mentioned before and i have to agree. It's a really repugnant language and i hate the alphabet too, one of the worst languages i've heard and if it were to become extinct, i wouldn't shed a single tear, probably my most hated language.
Estonian is basically Finnish, but take everything away that makes Finnish unique and interesting and now you're left with a language that's not only unbelievably difficult to learn but also bland and soulless, also the worst baltic language.
Dutch is also another one which has been mentioned often. While i don't think it's worse than Arabic or even Estonian. It sounds like down-syndrome German to me and has the same problem as Ukrainian. It gets uglier and more unappealing the longer someone uses it
Every south-asian (not southeast-asian) language is worthless garbage with a equally terrible alphabet, which also made me realize whenever i heard a pajeet speak, it's always in their main language, but the same applies to anyone from the indian subcontinent
