Sprouche is a combination of the words sperm and douche. While technically not a douche, sperm is substituted in place of the usual vinegar and water. The sperm is inserted typically by intercourse and usually mingles with other materials (vaginal discharge, lube or feces) in a vaginal or anal orifice.
