A doof is a rave, otherwise known as techno party or dance party. The name comes from the sound of a 4/4 techno beat. I never heard this term used before about 1994. A crew called DCP put on a party simply called "doof" at a warehouse in Brunswick (Victoria, Australia). The music that was big at that time was Gabba and hardcore. If you are familiar with these genres, you know the sound -
"doof, doof, doof, doof-doof
doof, doof, doof, doof-doof
doof, doof, doof, doof-doof
doof, doof, doof, doof-doof
doof, doof, doof, doof-doof
doof, doof, doof, doof-doof
"
Now, I'm not sure where the term actually originated, but after that party, the label stuck. We used to just call the parties "raves" until then. I have noticed that doof is more likely to refer to an outdoor party, while "rave" usually refers to a party in the city. An Australian species is the
bush doof, which is truly something to behold. Go off. Go doofing.
