Zebs.fesh.stekenda defect 

A German phrase that means, a self-hiding problem or defect. It describes a frustrating and commonly encountered situation, where you try and show someone a problem(or anomaly or defect) that you've been experiencing or observing, But you can't reproduce or demonstrate the problem because the problem or defect has seemingly MAGICALLY disappeared and everything functions or appears as it should!! (leaving you looking confused and feeling really stupid). These days it is most commonly a problem with your phone, computer or some kind of device (but it could be a problem or anomaly that you are experiencing or observing with anything really e.g. an abstract idea, an observed event, concept or demonstration).
<<Zebst.fash.stekenda.defect>> is a simplified phonetic pronunciation of the German phrase - Selbstversteckender Defekt - which means "Self-hiding problem or defect"
