Poor Shooting Disease (PSD) 

A basketball term where a team simply misses a ton of shots. This can be because the team is actually bad at shooting or because they are in a random shooting slump. PSD is not usually a terminal. Symptoms will start to wane and the team will eventually be healed. Their shooting averages will revert to normal. If the team is just bad at shooting basketballs, they will die a slow and painful death in the form of lost games due to PSD.
