firstly wdym with "if you are engaging in space where English is the dominant language" ?
the example I gave is done in Portuguese in a crowd, English is not the dominant language in that situation and BRs don't expect understanding of anyone else
and for the other cases, I'm not going for the "its our culture" thing bro, because I'm talking about BRs calling out death threats from other BRs. If a BR joke or slang was mistranslatled as a death threat, no other Brazilian will call the guy out because we know what he really meant. At max, you'll find BRs explaining foreigners about the misunderstanding, which I see a lot happening in vlr at least
