What does "passing craze" mean?
Native speaker’s answer

A "craze" is a popular trend or fad, so a "passing craze" is something that suddenly becomes popular but will die down over time. The speaker has used it here to say that "Hakuna matata," as both an expression and a mindset, is something that is eternal and endearing. It won't be like passing crazes, which will be popular for a while and then disappear over time. Ex: I think Tik Tok is just a passing craze for youngsters. Ex: I think the hype around this product is fake. It's just another passing craze.
