When a male ejaculates on a female's stomach, and semen remains in the depths of her bellybutton after the wipe-up process... allowing micro-organism to abound within.
Guy: "What is that goo in your belly-button?"
Girl: "My ex gave me a San Diego Tide Pool and I'm waiting to see if my sea-monkeys will grow inside".
Guy: "I've always wanted a sea-monkey".
