Roman Plunger
Usually performed by an Italian plumber - it is the act when a man vomits into the vagina of his female partner, and then proceeds to engage in violent intercourse, splashing the vomit everywhere until the classic "whoosh" noise from a freshly plunged toilet is made.
I was going down on Debbie before I drilled her, but the nacho supreme from dinner made me ill - I puked but didn't want to leave her hanging so I gave her a Roman Plunger and sent her home.
