My guy friend kissed my hand?

So today me and my guy friend were in class playing around and he would like flick my head or something stupid, like he would kind of put his hand on top of mine and like tap my finger then at random he grabbed my hand and quickly kissed it and I don't know what to think, he does a lot of other stuff too that makes me think he could like me, what do you think?
