How can you drop hints to a guy that you like him?

Okay the best thing to do is flirt!!! Don't do the Stupid perverted flirting (grabbing his butt, penis etc). Do the traditional twirl your hair etc. Just basically show an interest. Get to know him. One thing to keep in mind is, DO NOT get your friend to tell him you like him!! This tends to turn guys off, like you do not really like them.
