A method I use alot,also because it allows Kino is once you've opened and hooked the group or whatever term it is and u have hit it off with everyone ask your target "hey how much do u weigh?" she'll probably ask why or whatever, then say "cuz i'm trying to pick up chick, ahhhh whatever (then scoop her up, pick her up whichever is practical) and move her to another location in the venue, maybe even yell over ur back to her group that the two of you will be right back, "i'm just going to toss this one back in the water, be right back"...something like that.
