"Congoid juice" refers to semen of Congoid Negro specimen. It seems that there is a market among degenerate Whites, specifically among "metalheads", to taste various types of semen based on race, hoping for unique flavors or kicks. It doesn't take much intelligence to figure out how foolish and depraved this is. Black metal and elitism go hand in hand. We detest degeneracy, weakness, dysgenics, race mixing, and anything else which weakens humanity.
