Humbug. In English the word Humbug refers to a person or thing that tricks, deceives, talks, or behaves in a way that is deceptive, dishonest, false, or insincere, often a hoax or in jest. The term was first described in 1751 as student slang. 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.
