ways to flirt without making in to obvious: occasionally wink at her compliment her every once in a while tease her without being mean about it crack a cheesy joke and make her laugh hug her... or like, surprise attack hug her just make it cute not weird... make silly faces at her from across the room share food with her. girls freaking love food. those cute pick up lines always work on us girls... haha here ya go!! hope this helps :)
Watch how Al Pacino does it to Charlize Theron in the movie The Devi's Advocate! Good technique! Don't even need a wingman for that! Of course it does help if she is wearing something that exposes her neck and shoulders. But, if you really wanna play "unfair" then do what the Merovingian does to that blonde chick in the second Matrix flick! Works every time!
Look at her for a while if she asks you a question before answering Tilt you head Get caught looking at her Tell a joke when shes around Have an inside joke w her Text her w smiley faces Tease her lightly (not too much it will run off the wrong way) Hope i helped. Leave me a comment if u have a question
