The direct translation of this term is "spray the wall." It refers to the practice of the Batoro people of Uganda where adult women teach younger women to ejaculate. Younger women are not considered eligible for marriage until they have mastered this technique. While female ejaculation is a popular theme in adult movies, and there have been books explaining the physiology of female ejaculation (including Eve’s Secrets by Josephine Lowndes Sevely), some scientists still debate the nature of female ejaculation.
