Top definition
A difficult sexual maneuver whereby a female completes multiple back-spins naked while becoming so aroused as to cause a fountain like spray to emanate from her vagina. The spray should land in a perfect circle just outside the circumference of the back-spins.

Female military members must throw a salute just above the vagina during the maneuver to earn full credit.
Her Circle Geyser was so perfect, I threw a penny into her vagina and made a wish.
