A kiss is the act of pressing one's lips against the lips or other body parts of another person or of an object. Cultural connotations of kissing vary widely. Depending on the culture and context, a kiss can express sentiments of love, passion, affection, respect, greeting, friendship and good luck, among many others. In some situations a kiss is a ritual, formal or symbolic gesture indicating devotion, respect or greeting, as in the case of a bride and groom kissing at the conclusion of a wedding ceremony or national leaders kissing each other in greeting, and in many other situations.

Depending on the culture, relationship and context, a person may kiss another on their lips, cheek, head, hand and each of these gestures may carry a different social significance.

The word came from Old English cyssan (“to kiss”), in turn from coss (“a kiss”).

Kissing on another person's lips has become a common expression of affection among many cultures worldwide. Yet in certain cultures, kissing was introduced only through European settlement; prior to this, kissing was not a routine occurrence. Examples of this include certain indigenous peoples of Australia, the Tahitians, and many tribes in Africa.

Ryan Daniel Montgomery (born July 5, 1977), better known by his stage name Royce da 5'9", is an American rapper. He is known for his longtime association with Eminem and for his solo career, recording primarily with Carlos "6 July" Broady and DJ Premier, as well as ghostwriting for the likes of Diddy and Dr. Dre. Royce is one half of the rap duo Bad Meets Evil with Eminem and also a member of hip hop group Slaughterhouse. The editors of About.com ranked him #33 on their list of the Top 50 MCs of Our Time (1987–2007).

Ryan Montgomery was born and raised on the West side of Detroit, Michigan on W. McNichols & Wyoming Ave. He moved to Oak Park, Michigan when he was 10 years old, later acquiring the nickname "Royce" during high school after wearing a Turkish link chain with an R pendant resembling the Rolls Royce symbol. He started rapping at age 18, influenced mainly by Ras Kass and Redman. He signed his first deal in 1998 with Tommy Boy Records, after the label shut down, he signed a deal with Columbia where he started recording an album called Rock City, referring to Detroit's former status as home to Motown Records. When the project was heavily bootlegged, Royce left the label for Koch to re-record some of the album, eventually releasing it in 2002 as Rock City (Version 2.0). While the album did not sell very well, the DJ Premier-produced single "Boom" gained Royce some underground recognition and eventually resulted in the two working together more closely.
