What is the condition called where the bone is sticking out of chest?

Pigeon chest? It can be hard to tell from your description, but i'm wondering if you're asking about something called pigeon chest, or pectus carinatum. It's a condition where the sternum and ribs bow out, instead of lying flat. You can read more about it from a reputable source here: http://www.Nlm.Nih.Gov/medlineplus/ency/article/003321.Htm.
