Is teasing a major sign of attraction?

when a guy teases a girl constantly , like , almost everything he says to her is teasing . for example : he teases her about any outfits the girl wears , the way she talks , the way she walks , but not in a mean way , he teases her in a really friendly way , is this a major sign that he has feelings for her specially if they're best friends or there are guys who are just like that ?
