What is flirting? Flirting is a social interaction where people subtly suggest they are attracted to each other. For example, a woman playfully making fun of a man’s fashion could possibly be flirting. Flirting can be fun and is often one of the first steps to starting a relationship. Flirting, however, can also happen in a long-term relationship. In a long-term relationship, flirting is simply a kind of playfulness.
