Can slavs understand each other without translate?

[Ülev]

If i'm not a Slav, why do i squat so much?

cause it is not slavic thing, it is "Steppe Warrior" feature, all the days on horses etc.

because Poles and Belorusians are Slavicised West Baltic tribes

Российские генетики: белорусы и поляки - близнецы-братья, а русские даже не славяне / Russian genetics: Belarusians and Poles are twin brothers, and Russians are not even Slavs

If i'm not a Slav, why do i squat so much?

from that article:

РУССКИЕ ОКАЗАЛИСЬ ФИННАМИ / Russians turn out to be Finns

Оказалось, что генетически население Восточной Украины – это финно-угры / It turned out that genetically the population of Eastern Ukraine is Finno-Ugric

Сам факт генетической идентичности поляков и белорусов – не является неожиданным. Сама история наших стран есть ему подтверждение – главной частью этноса белорусов и поляков являются не славяне, а славянизированные западные балты, но их генетический «паспорт» настолько близок славянскому, что в генах практически трудно было бы найти отличия между славянами и пруссами, мазурами, дайнова, ятвягами и др. Именно это объединяет поляков и белорусов, потомков славянизированных западных балтов.

The fact of the genetic identity of Poles and Belarusians is not unexpected. The very history of our countries is confirmed it - the main part of the ethnos of Belarusians and Poles are not Slavs, but Slavicized Western Balts, but their genetic “passport” is so close to Slavic that it would be practically difficult to find differences between Slavs and Prussians, Masurian, Dynova in genes , Yatvyagami and others. That is what unites the Poles and Belarusians, descendants of Slavicized Western Balts.

and

Такое ближайшее родство западных украинцев с татарами, возможно, объясняется сарматскими корнями древних жителей Киевской Руси. / This close relationship between Western Ukrainians and Tatars is probably explained by the Sarmatian roots of the ancient inhabitants of Kievan Rus.

Macedonian and Torlakian - yes, almost every word.
East Slavic languages and Serbo-Croatian - can catch the meaning of the conversation, but don't understand everything.
Slovenian - depends, sometimes only spearate words, sometimes can catch the meaning.
West Slavic - only separate words.

Most of the time I understand Serbs and vice versa.
I understand part of Polish speech but far from everything.

[Terminator98]

Most of the time I understand Serbs and vice versa.

То волим да чујем, брате.

То волим да чујем, брате.

Удоволствието е и мое.

Also, I like it when Serbs say ''Чуваj се.'' - here used to mean ''Take care.'' or, as we Bulgarians say, "Пази се.". Terminator98 meant literally ''to hear'' in his post though (using a different meaning of the word).

[Crn Volk]

Bulgarian and Serbo-Croatian yes, Slovenian more difficult. West Slavic and East Slavic difficult to understand.

[Mortimer]

I tried to understand russians and could a little bit.
