Eskimo kissing

An eskimo kiss in modern Western culture is the act of pressing the tip of one's nose against another's. It is loosely based on a traditional Inuit greeting called a kunik.

A kunik is a form of expressing affection, usually between family members and loved ones, that involves pressing the nose and upper lip against the skin (commonly of the cheeks or forehead) and breathing in, causing the loved one's skin or hair to be suctioned against the nose and upper lip. A common misconception is that the practice arose so that Inuit could kiss without their mouths freezing together. Rather, it is a non-erotic but intimate greeting used by people who, when they meet outside, often have little except their nose and eyes exposed.
