An entirely dumbass and retarded way of saying WTF or What The F***. If you are saying this you are too stupid. Sometimes this is pronounced with a "Goofy" voice. Dafuq is also for little children who are afraid to say the entire phrase out loud. If you are one of those dicktards who uses dafuq, STOP because you are making a complete and utter tardhead of yourself. Dafuq is also commonly used to annoy the shit out of anyone who has any common decency. Dafuq will also make any grammar nazi kill you. GG.
