orginally coined by Homestar Runner, and used in mostly non sensical situations, no one is absolutely positive on the actual meaning of the term, although it has led to some speculation. Providence College scholars have listed as either
1. Alchohalic beverage
2. Female ejaculate
1. hey man, pass the witches brew

Witches brew is a family term for coffee. The stronger the coffee, the more it deserved the name of "witches brew". I think it got this name from the strong flavor of the coffee and the busy behaviour of people who drink too much coffee.
Mother laughed as she poured the hot liquid she called "witches brew" from the coffee pot into the porcelain mug. "Here", she said, offering me a cup of her famous witches brew.
