If there is something that might be happening without you noticing, it is a man or a woman working up his or her flirt on you without you realizing. It is not hard to know when you are at the center of his or her schemes, just in case you are about to miss a wonderful chance to have a great guy flirting with you.

Eyebrow Lift If a guy sees a female he's attracted to, the chances are his eyebrows could rise and fall quite quickly. If this happens, try to flip an eyebrow back at him in case you're interested. This is a vivid signal both ways.

Gains Attention A guy about to flirt with you wields exaggerated gestures or movements usually to the effect that he's trying to be different from the others who might also be interested in you. He could be shifting positions such that he might be standing slightly disentangled from his group of friends or people.

Parting Lips Another obvious sign of his need to flirt with you is his lips might automatically part for a couple of seconds once your eyes have met for the first time.

Nostrils and Face If the man is interested in you, it is possible his nostrils might open slightly as his face widens a little. As the eyebrows rise and the nostrils send a slight flare and a part of lips, he could have obvious and friendly expression lighting up his face.

Classic Courtship Male Stance It is possible that he could have a macho stance more so a cowboy style, as he might probably lock his thumbs inside his belt as he points fingers downwards and spreads the legs about, and the shoulders a distance apart tilting his head towards one side. It is a classical way for a man to flat, as if in command of his territory and to give a confident approach to the whole affair.

Touches his Face Another sign of his flirting is the fact that he might begin to rub his chin as he brushes his cheek using the back of his fingers and sometimes touches his ears. It is possible he might not realize it but it is a holistic combination of his nerves and an unconscious preening behavior.

Strokes Shirt Front or Smoothes Jeans This depicts the true move for a flirt as seen by more unconscious preening, from smoothing his shirt sleeve, shirt pocket or tie. This is equivalent to the girlish lip lick while in the same position.

Fiddles Hair A man attracted to a female might tussle or smooth his hair involuntarily. This might be done more occasionally than you might realize as another preening behavior for a female.

Adjusting Socks If a man adjusts or pulls up his socks in the presence of a female, it is a sure and generally a hundred percent sign that he is more than interested and is trying to look the best he can. It is a very vast preening signal.
