 Flirting usually involves speaking and behaving in a way that suggests a mildly greater intimacy than the actual relationship between the parties would justify, though within the rules of social etiquette, which generally disapproves of a direct expression of sexual interest in the given setting.This may be accomplished by communicating a sense of playfulness or irony.Double entendres (where one meaning is more formally appropriate, and another more suggestive) may be used.
