look up any word, like the eiffel tower:
A medical condition characterised by head pain due to repeated violent coughs.

A person is said to have a coughcussion (or be coughcussed) if they have both a throbbing headache/migraine and a violent cough - the intensity of the cough causes additional head pain.
