Well, this could mean many things.
IT means he thinks your cute or hot
She is really into you!
it mean's they like/love you and they wanna have sex with you
that is stupid, but it means that the girl is jealous that you are looking at another girl's foot and not her own... at least its only a foot
It is when your foot is turned out in back right behind your ankle and only your heel touches.
If a girl always rubs your stomach and touches your belly button, it could mean she likes you. One day you should ask her why she does it just to see what she says. If her advances are unwanted, you should let her know.
A foot fault is when you serve and your foot touches the ground on or or forward of the service line before you strike the ball.
Maybe hes rubbing his eyes to double-take because of how beautiful you are
it means she really LOVES you she wants to have every thing for the twoof you
It means that he isn't ready for a committed relationship.
Arch.
A guy may rub a girl's waist if he likes her. A guy may also do it accidentally when walking by and it may not mean anything.
