Matt: She was never into him in the first place. I can't believe that he's still upset about me hooking up with her; he's been boxing out for an entire week now.
Darryl: Nah, he's not coming out tonight. He's staying in to play video games. He totally boxed out on us.
Brice: He said that he MIGHT show up. Chances are that he'll just box out.
