A Craig
A Craig is a guy who will do anything for you, but he'll probably forget to call you and text your ex. He's like a superhero, but he's also a total mess.
You: I'm sad. Craig: I'm not sad, I'm just being cool.
You: I'm the best. Craig: I'm the best, and I'm not even trying.
You: I'm going to the party. Craig: I'm going to the party with your ex.
