Humbug is a person or thing that tricks or deceives or talks or behaves in a way that is deceptive, dishonest, false, or insincere, often a hoax or in jest. While the term was first described in 1751 as student slang, its etymology is unknown. It is now also often used as an exclamation to mean 'nonsense' or 'gibberish'. When referring to a person, a humbug means a fraud or impostor, implying an element of unjustified publicity and spectacle. In Britain, the term is also used for certain types of candy.

Unsinn, auch Widersinn ist ein von Sinn und Logik gelöster oder grob falscher Sachverhalt – bisweilen (absichtlich) scherzhaft.
