Chip on Your Shoulder

"Is that a chip on your shoulder? It's a sizable chip. Must make it hard to walk. It's better to be light on your feet. You should lose the chip… No, it's not an asset... Really... OK... If it works for you, I guess, I'd say, 'different strokes for different folks.' You gonna dare someone to knock it off? That's just that old macho bullshit.  Really? Are you sure? A chip, right? On your shoulder? Hah!"
