It's not quite a crush. It's more than admiration. It's less than adoration. It's not sexual, and yet you want to know everything about them.
It's when you've made a friend, and you begin finding out the insanely coolest things about them, and suddenly you're talking about them to your other friends, or even your family. People start giving you weird looks because, like, do you have a boner for them or something? Jeez, if you like them so much, why don't you marry them? And you want to scream, DON'T YOU THINK I WOULD IF POLYGAMY WAS LEGAL AND WE DIDN'T HAVE SEX BUT JUST LIVED IN FRIENDSHIPY BLISS??
There should be a word for that.
