Not necessarily
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 is jealous.
it means that they may be into you.
He want to flick your bean or if your a guy he wants to toung punch your fartbox!
he's just probably jelous that he didnt get you before the other guy did. that or he doesnt have anything better to do.
He wants you to tease him (if u r a girl)
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...
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.
Usually means they are interested in you
if you like the guy, lead him on and hopefully he will like you.
They say if he teases you.
