Dictionary.com defines flirting as "to play at love" or to "act amorously without serious intentions." No matter how you say it, flirting means showing another person that you're interested in them, whether it's casually or more intimately. Flirting gives both people a confidence boost by making the flirter feel outgoing and the flirtee feel desirable. Flirting online may seem harder because there is no physical interaction, but with the right skills you can achieve the same feeling as the real thing.
