I absolutely agree with you on that! If I had my life over, I would have loved to have studied linguistics, it's a fascinating topic!
Some slang words/terms are very satisfying to use in everyday conversation, "lor" sounds like one of them!
PS that conversation of SA slang is not a very polite one, and although some of the words are very expressive, it's not my type of lingo🙉...I didn't say it😅
