When you're trying to connect with your crush, you want to make sure that you make a good first impression, because those are hella important.
You don't want to just message them out of nowhere on Facebook and say, "sup," nor do you want to awkwardly approach them and face the ultimate fear: in-person rejection.
You want to send a clear, creative message that you're interested in them. And there's tons of ways to do that. You could stand outside of their window holding a radio above your head playing their favorite song. Or dress up as a green man and run on a baseball field, proclaiming your love for them. Or you know, you could try a cool pick-up line, but I've never been good at those.
