A man that can not make a decision. He is always sweet at first, and then does a complete 180. Usually has erectile dysfunction and doesn't even seem to know it. Becomes fat as they age, and will inevitably go no farther than a couch in the garage. Beware a Charlie always looks used and abused before he reaches thirty. Worst part, he is still too dumb to realize it's his own fault.
Person 1: Why do I recognize you?
Person 2: I'm...uh... Charlie's ex.
Person 1: Umm, really?
Person 2: Yeah, I know, Charlie Aaron was the worst mistake I ever made.
