A depraved sex act performed at the culmination of oral sex. The standing male ejaculates in the receiving woman's mouth, and then quickly punches her in the stomach before withdrawing the penis. The resulting semen shot out each nostril bears a resemblance to walrus tusks. The Frothy Walrus is most often performed as a surprise maneuver, and is inherently non-consensual.
