Stoney dipstick
A sexual maneuver involving two partners. The partners begin in the "missionary" position. After the partner on top has finished having intercourse he stands over the other pointing his penis towards his partner's mouth. He then proceeds to "dip" his penis into her mouth as if he were checking her for oil, often exclaiming "Bloop!"
After he finished giving Alana the business, he hopped up on his feet and gave her a Stoney dipstick. Bloop!
