"Bills and coo" is a colloquial expression used to describe the affectionate and tender behavior of a couple, typically seen among birds. The phrase derives from the courtship rituals of some avian species, particularly pigeons and doves, who engage in a specific display of behavior known as "billing and cooing."
This behavior typically involves the birds touching their beaks together, often in a brushing or nibbling motion. It is accompanied by softly murmured sounds, usually low cooing noises, created by the birds to communicate their affection and build their bond. These actions are symbolic of intimacy, tenderness, and care between the birds.
Metaphorically, the term "bills and coo" is often applied to human couples who exhibit similar behavior. It describes the couples who engage in loving gestures, gentle caresses, and affectionate murmurs in order to maintain a close, loving relationship. It signifies the affection, tenderness, and strong emotional bond shared by the couple.
The phrase is often used in a positive or endearing context, depicting the sweetness and harmony within a romantic relationship. It implies the presence of love, care, and adoration between two individuals and is commonly used to describe couples who openly express their affection and maintain an intimate connection, akin to the tender nature displayed by birds during their courtship.
