I have this friend who is a natural in every meaning of the word and one night I was observing him. He would talk to girls and about five min. in the conversation he would whisper something in there ear. Then all of a sudden a big smile would go across there face and they would follow him around all night, it was crazy! So one night I asked him what he said to these girls and he said that was for him to know and me to find out. I was pissed I bugged him for a month strait. Then one night I figured it out! YOU SAY ANYTHING! thats not creepy anyway. Girls love it when you whisper in there ears!

Ive whispered negs in there ears like "your feet are kinda big for a girl your size but at least your toe nails are painted nice" then boom smile, hit on the arm.

I've made fun of other people in the room while whispering in there ears!

Ive said things like "follow me to my car I need to show you some pictures of my vacation."

Ive found out that giving a little wave to come close and whispering in there ear works better than just strait up talking. plus it gives you excuse to touch her shoulder.

you can say anything! Telling dumb little secrets and statements are the best but questions are good too.

Ive even whispered in my targets friends ear saying "your friend keeps staring at me?" while looking at my target and that bugs her cause she knows its about her and she wants to know what i said? then I whisper in the targets friend again "she still doing it"

Its been like magic for me in any group setting.

Hate to tell you this but i been doing this for a long time and it does work. And yup you're right about negging them while whispering, They laugh and i get hit and then i'll say " you wanna fight ?
HB: "You're so mean"
ME: "Then we have make up sex"
Me: "HAHAHAHA ooo noooo"
Me: whisper"I'm Kidding we don't need to fight make up"
HB : HHAHAHAHA
