The word "moff" derived from the southern part regions of Africa and is used to describe a form of state or being (hungover, tired, wasted etc.). This form of communication has been adapted in the creation of slang between the german, afrikaans and english speaking cultures in regions like Namibia, Botswana or South Africa.
