A brightly optismistic interjection that encourages hope and happiness, while diminishing all that is evil, sour, depressing, inconvenient, and painful about life. This magical interjection usually provokes a smile. It is the verbal antidote to any form of negativity. It is the sugar in the lemonade.
Person 1: Oh no! I didn't get my work done today, just as I never do. On top of that, I have to replace my flat tire and find some way to lie my way out of jury duty. Oh, and my girlfriend just discovered that I've been calling my ex. And yeah, I've got food poisoning too, and I think my appendix just burst.
Person 2: I know, it's a tough day. Positive Apples!
