look up any word, like bukkake:
When sick with the common cold, the booger bone is the biggest booger that is responsible for the production of other boogers and mucus. When one sneezes, blows, or otherwise ejects the booger bone from one's nose, the cold has been defeated and the individual should recover from his or her cold shortly thereafter.
- I think this cold is going to end soon- I just sneezed out the booger bone.

- I just blew the booger bone right out of my nose!
