according to wikipedia, flirting is an expression of sexuality and a common form of social interaction whereby one person obliquely indicates a romantic or sexual interest towards another. It can consist of conversation, body language, or brief physical contact. It may be one-sided or reciprocated (encouraged) with intentions of getting to know that person on a higher level.
