It's pretty obvious that he wants some kind of relationship with you, friends or more. Maybe you could make the first move.
Their a dick and might have been dared into talking to you.:D
He will rather act mean or try to make you laugh
Well, it really depends on the person, if the person does it out of no where they might be trying to make you laugh or smile back, if it's someone who always talks to you and they are the opposite gender, they have a crush on you
it means that thay like yhuu !!
he told a funnier joke than you did.
In fact, he's wanting to laugh, and is using you to make him laugh too.
Yes. He always laugh at your jokes I mean, who wouldn't :)
Sounds like he likes you a lot.
I think it means that they bet they can make you laugh.
Unfortunately guys are complicated and the signs they may put out are not always obvious or what you would think. This isn't the best one to judge by... he could just be interested in what your saying. Watch for more obvious signs such as he always talks to you, makes excuses to be with you, touches you on the arm, tries to make you laugh etc. to see if this guy is into you.
Not always. If it is excessive then they probably do like you.
That doesn't always mean she likes you, but she might be interested.
