How to determine if the guy is flirting you

Guys flirt and so do girls. I personally think guys flirt more (for sure). Why I had this in my mind all of a sudden? Well I was in an exhibit for few days and as usual guys love to "talk" to "new" gal or call her babe / beautiful/pretty / sexy or even buy her lunch. Sometimes u find it sweet but could be annoying also.

Well, how do you determine if the guy is flirting you ?
1. He will compliment you. Well how ?
Hey are you new here? Never seen u before? Your so beautiful and hot. Btw nice dress!! (Even if he doesnt mean it)
2. He will try to make you happy
Girl : Sigh !! didnt manage to win any lucky draw for last nite event. I never hv the luck!!
Guy: Well now you have me and Im ur lucky star ;)
3.Smile at you sometimes. Smiling is definitely the most effective tool in your flirting toolbox.
4.Look at you !! It doesnt matter if your looking or not, he will study you from head to toe. Actually is head to boobs to thighs to toes.
5.They will act like they are a REALLY close friend to you. So understanding, so caring and so sweet.
6. Guys will do small touches such as a small pat on your head, shoulder or cheeks.
7.He will share at least a joke especially lame one to you everyday and when joking he will try to lean towards you and brush through your hair.
8. When a guy is flirting, hes attention is only on the girls. He would ignore everyone else in the place and lock hie eyes on as if your the apple of hes eyes.
9. Some guys will use this old method - Teasing to catch your attention. He would not restrict himelf to a regular conversation but he will try to tease you so that you hold on to the talk and react more.

I dislike guys who flirt but Im always victim in this "flirting" process. Sigh !! LOL.
