A Pro Apo is a PROfessional Apologizer. Their life isn't quite in order and thus causes them to frequently apologize for something. They're not very reliable. Sometimes people don't mind being a Pro Apo and they make a lifestyle out of it, while others may be stuck in a rut and are trying to figure out how to get away from being a Pro Apo. Beware, the career Pro Apos may be really good at apologizing and making excuses.
Aiden forgot to get me a gift for my birthday, Christmas, and Valentine's Day. Not sure if he's an asshole or just an absent minded Pro Apo... probably both.
