(n). Love can be the happiest, most exuberant time of your life. It can also be a disease. It can mean terrible heart break. It can mean years of heart wrenching sobs without rest.
It can mean that you have now entered the world where the girl of your dreams can/will/already has crush(ed) you like a bug and make your life a living hell, but you still continue to pawn after her like a lost puppy because that's all you're ever good for. You know she won't go out with you because she's way way way out of your league and way way way too perfect for the likes of your sorry ass. But she'll never tell you that and leave you to have fantasies of her and you together. That's the truest meaning of the word.
Girl 1: "Oh man, I'm in love with her"
Girl 2: "She will crush you harder than the dirt under your shoes"
Guy 1: "Oh man, I'm in love with her"
Guy 2: "She's the only girl who won't get in your pants"
