He is jealous.
it means that they may be into you.
He likes you.
He want to flick your bean or if your a guy he wants to toung punch your fartbox!
If a guy teases you it's because he is the spawn of the devil and wants to be mean to you. You will then probably think he likes you so he will have sex with you and then crap on your chest after wards and leave you
He wants you to tease him (if u r a girl)
Well it most likely meens that he likes you but is trying to see if you are even intrested at all in this guy to see if he has competition.
Not necessarily
It means the guy's friend has a thing for you, he likes you but knows he can't have you, so he teases his friend about you.
If someone teases you it may mean that he fancies you. If a guy teases you it usually means he wants to get your attention or see how you react. When he teases you, just smile at him. However, it doesn't always mean he likes you. It may be the opposite. I suppose it depends on whether the teasing is mean or not...
That they like you or they are being sarcastic or that they are playing with you. It all depends on how and when they said it.
It depends on what you actually did. It can be a sarcastic expression.
