Eskimo kiss
An Eskimo kiss, nose kiss, or nose rub is a gesture of affection where one rubs the tip of one's nose against another person's face. In Inuit culture, the gesture is known as a kunik, and consists of pressing or rubbing the tip of one's nose against another's cheek. In non-Inuit English-speaking culture, two people Eskimo kiss by rubbing the tips of their noses together. Nose-to-cheek kisses are found in other cultures as well.
