1) noun - a type of nonsense that is spoken, often by accusation (see example).
2) adjective - * due to the primative environment which words such as 'fraff' are used, it is hard to distugnuish between the adjectival form of the word and the noun; however, something may be described as being 'fraff'. When referring to an idea or statement of somebody, the word will adopt a meaning implying untruthfulness, and perhaps indicating the unwillingness of the person on the receiving end to accept the idea as being sensible.
1) "Stop chatting fraff, and get on with it."
2) "It was all fraff, he doesn't know what he's talking about."
