Sometimes a nudge is just a nudge. ---- when she nugde u and u look at her and she smiled then yea it depends on the situation. if she did a playful nudge, it shows that she's comfortable around you, or that the two of you have a close enough relationship.
It means he likes you.
of course it does,i have alot of guy friends i know this one
Well if a guy pokes you in the arm it means he either wants you attention or he is trying to annoy you both are considered flirting
it means you can't move them
That is just a loose term, similar to 'branch' or 'region' indicating a division in science.
She likes you.
no it means hes a player
It could.If she hits you hard then she probably doesn't. If she hits not so hard and on the arm she probably likes you.It depends on how she messes around with you.
A girl may hint that she likes you without saying it directly by touching your arm and having extended eye contact with you.
He wants to cuddle
It could mean that she would like to get to know you a little more, that she likes your company and that you should TALK TO HER!
That would be a pretty clear sign that he likes you.
it means he likes you.
She likes his muscles.
It can mean that he likes you or that there was not enough space in the hallway.
Touching someone on the arm or leg while talking is just a sweet gesture. Maybe the girl doing it likes you.
It could just be a friendly thing, or it could be because she likes you. I wouldn't ask her unless she shows other signs though.
