A sexual-act made popular in underground fetish clubs in Europe. It involves a female getting menstruation blood onto an umbrella. The umbrella is then opened and twirled at a rapid rate; causing the menstrual blood to fly off. Some western versions of this act involve the umbrella being inserted inside the menstruating female but many of the rainmakers founders frown upon this addition.
