DICAF (pronounced decaf) is an acronym coined by boxing Youtuber Dontae Williams. It's meaning is self-explanatory by what the acronym stands for: Dumb Ignorant Casual A** Fan. Casual boxing fans who don't know what they're talking about because they lack the understanding of the nuances of the sport and/or its politics will usually be labelled a DICAF. However, this adjective can be used to describe fans of other sports and genres.
