(verb) A tricky femdom sexual maneuver that is set into motion by the male thrusting from the top in the missionary position. Without warning, the female partner flips him over onto his back, pins him down, and inserts her index finger into his anus. His prostate is unceremoniously pressed and he's made to expel his seed onto the sheets instead of into her.

Made famous by Cerina Vincent in the 2002 horror film Cabin Fever.
Rumor has it that Miranda performed a Cerina on her husband on their wedding night, and that's why he has her last name.

Marcy smirked smugly after she Cerinaed Paul.
