Rosborough is a painting medium that not only includes paint, but also shit, semen, and blood.
The best way to make Rosborough is to receive anal sex, have the giver make it really rough so you bleed, allow the giver to cum in your ass, then shit the mixture into paint, and mix it up. Voila, Rosborough.
