I heard the same thing all the time when I was a kid. “You have a chip on your shoulder kid!” Yeah so? *Turns head and takes a giant bite out of it.* Now I have half a chip on my shoulder. And a bunch of crumbs.
This Chip On Your Shoulder Halloween Costume put a giant chip on your shoulder. Ruffled, because they’re the best. Possibly Lays. If I could lick it I would know for sure.
