Schmilblick

Schmilblick is a word that was invented by a famous French comedian Pierre Dac, and it refers to a fictional object that you don't know what it is. Imagine if you're playing a game with your friends and someone mentions a mysterious item that you've never seen before, but you don't know what it is.

Schmilblick is used as a joke, and it's often said when people talk about things they don't know or understand. It can be compared to the English term "thingamajig" or "whatchamacallit."

So, for example, if someone asks you if you know how to fix a computer, and you have no idea about it, you can say, "I'm not sure, but maybe you need to adjust the schmilblick." It's just a funny way of saying that you don't know what to do.

In summary, Schmilblick is a made-up word used for something that you don't know what it is, and it's often used as a humoristic expression.
