Agreed, this is the correct South Slav phonetic Cyrillic spelling. Also "бејзд".I think a different cyrilic variant for "cringe" works better for the closest spelling, such as "кринџ", which phonetically sounds identical to the original pronounciation of the english word, apart from the thrilled "r".
But it's wrong, pretty or not.Wouldn't look as nice though, because "ж" is the most beautiful letter, also the whole drawing is awesome Jacob !
It's probably best for the sake of consistency if Jacob sticks with Russian and finds himself a Russian sidekick, or at least Bluehawk, if he proves he's not an Ukrainian agent.
