What do you say to a guy who you dont know if he asks you out?

Well then :)Well if you have a crush on him then like, talk to him try and joke about who he might fancy nudge him and like try and guess, say when you haven't said you, that's everyone and you've said no to everybody, and then say, oh ME? and if you don't just go straight up to him and say, look I don't know what you're going to do because you're acting like you love me, I don't love you sorry, if you do but okay?
