Lmao i wish it were that easy man . Unfortunately you have to do it without violating social norms . Better if you went up , made a joke to the group . Then said something like . I love making you all laugh but really i came over here to tell this one point to the girl that she was cute and she should give me her number , what do you guys think ? And if you made them laugh once they will all say omg yes yes . Then you should probably stick around another few mins to show them you are a cool and normal guy . Anyway , this is all theoretical stuff . The best way to understand this stuff is to become more self aware because it will make you be more honest with yourself and intentions , while at the same time allowing you to not cross social boundaries in different contexts . If you dont already , try meditating just 20 minutes a day . For me , meditating helps in the exact way I explained helping me find the balance between cocky asshole and fun nice guy that every girl loves .
