معلِشّ is used to downplay a situation, whether to console, sympathize, or apologize. The word originally comes from the Modern Standard Arabic phrase ما عليه شيء, which literally means nothing against it.

كِده is likely the most quintessentially Egyptian word there is. Not only is it very high frequency in everyday speech, but it is unique to the Egyptian Arabic dialect. كِده is related to the Modern Standard Arabic word هكذا like this but takes on a range of idiomatic meanings on its own and in phrases.
