Flirting

Classic flirting behavior involves letting someone know you like him or her and that you'd like to pursue it further. Not surprisingly, body language plays a huge part in this game, and even less surprisingly, so does eye contact. Dozens of little gestures are used to send out sexual messages: the tilt of the head, holding eye contact a little longer than normal, the angle of the hips and the hands through the hair. Glancing sideways is a gesture that can suggest doubt on its own, but combined with a slight smile and a narrowing of the eyes it is a powerful gesture of flirtation.

A man sends out signals with his swagger; a woman, by rolling her hips. A man loosens his tie ever so slightly; a woman moistens her lips. On and on, the parties convey their interest in each other through their stances, glances and postures until some small gesture synchronizes and sends the O.K.
