A lewd sexual act which involves a female giving oral sex. Once the male ejaculates and the female swallows, the male quickly chops the female on the back of the neck, and two seamen "tusks" come out of her nose.
She said she was tired of oral sex, so i livened the night up by slipping her a walrus.

After oral sex, when the woman or still has the semen in his or her mouth, you cover up the mouth, punch the participant in the stomach, and the Walrus is revealed. With the mouth covered, the semen must come out of the nose, giving the appearance of Walrus Tusks.

When a guy cums in a woman's mouth and then pinches her nose so she cannot breathe. This leaves her no choice but to swallow or spit it out. Thus creating the bloated cheek look of a walrus.
