When you drink coffee, you are sometimes overcome by a fit of coughing. In order not to choke, you spray the coffee from your mouth. The liqiud coming from your mouth, is known as COUGHFEE.

Mark: *Cough!*
Ashley: Coughsundheit, my son, coughsundheit.
Mark: What the heck?
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 throbbingheadache/migraine and a violent cough - the intensity of the cough causes additional head pain.

B. A Paladin playing World of Warcraft who never listens to his group members because he feels above them skill and experience wise. He often queues for random dungeons with a tank and said tank leaves group upon joining.
