A Mermaid's Purse is when an individual defacates into a womans vagina, the woman then hovers over the face of the individual and lets it fall onto his or her face.
John and Linda wanted to spice up their relationship so during sex, he took a hot, steamy, crap in Linda's vagina and she reciprocated by giving John a Mermaid's Purse.
