Flirting

Flirting or coquetry is a social and sexual behavior involving body language, or spoken or written communication between humans. It is used to suggest interest in a deeper relationship with another person and for amusement. Flirting can change in intention as well as intensity, whether it is harmless fun, or employed with the design of seeking a romantic or sexual relationship.

A person might flirt with another by speaking or behaving in such a way that suggests their desire to increase intimacy in their current relationship with that person. The approach may include communicating a sense of playfulness, irony, or by using double entendres.
