Usually means they are interested in you
Not necessarily
if you like the guy, lead him on and hopefully he will like you.
They say if he teases 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!
If he teases u YES if not NO
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
you can defanitly tell when the guy is always looking at you and if he is nice to u and sometimes if he teases you or picks on you
if he teases you alot but is quite close with you
Possibly, or he may just be friendly. Only you can decide that.
if the guy is teasing you about a guy you like he is probably showing a sign of jealousy that you don't like him so this guy might like you
