Flirtation refers to playful, often lighthearted interactions between two people that may or may not be romantic in nature. It typically involves teasing, joking, and other forms of verbal or nonverbal communication that convey a sense of attraction or interest without necessarily leading to any serious commitment. Flirtation can occur between individuals who are already involved in a relationship, as well as those who are single and looking for romance. It is often seen as a harmless way to express interest, build confidence, and create a playful atmosphere.
