Duffy

In the act of sex, when the male is ready to ejaculate, he pulls out and inserts the tip of his penis into the nostril of the sex partner. And ejaculates inside of the nasal cavity. Ending result is sperm dripping down the throat of the sex partner.

Judy: Hey Amber why does your nose look all red?

Amber: Oh he Duffy'd me last night again.
