When it comes to swear or cuss words there’s more cultural distinction than biblical instruction involved with the rules. Different languages have different kinds of taboo words for different reasons. So the Bible doesn’t explicitly state a specific word is taboo nor are there any Hebrew or Greek translations of swear words in English. Unless we are actually cursing or insulting someone, it is not a sin to use certain words. Words are just words, whether it be in some generic colloquial expression of pain or angst (what the f*ck or oh sh*t), or using a word in its proper contexts like referring to a donkey (ass), or female dog (bitch). A lot of our modern Western English swear words actually have legitimate context, so when using them in context it’s not an issue.
