"That's ur cheek!"

[El Don]

Some of you who like making girls feel like dorks might like this one..
Extend your hand out and tell her to do the same.. Then tell her to make a circle with her forefinger and thumb (also as you do it).. and then put the circle to your cheek while telling her "now put it to your chin"..
She will most likely follow you to which you respond "That's not your chin, that's your cheek!"  She'll feel pretty dumb when u tease her a bit..  It has worked pretty good for me..
Enjoy!
