Daffodilitis is a growing concern today among many people. Daffodilitis has a wide range of symptoms and many, many cases, but basically it can be defined as one being unable to perform or act with courage and pride and a desire to not look like a complete and total wussy. Most cases are usually accompanied by some sort of blame to take away from the fact that they're complete failures; performing in a very unmanly fashion.
