He could be flirtting with you.
Nothing
Cuz
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 ate him.
of course it does,i have alot of guy friends i know this one
It means he's into you.
It's a fun way of flirting, poke him back. :)
It means he likes you and or he was droped on the head as a child
Maybe he likes her.
They're just flirting with you, they think your cute! Poke them back if you like them! :)
You are doing exactly the same thing, what do you mean by it? The only way to know for sure is to ask him.
Ask him why he pokes you and if you don't like it tell him to keep his hands to himself.
