Diagnosis of the Kwashiorkored Giant

I know you still feel ebullient
But you have to watch your steps now
Cos you're not as powerful
Nor as strong, as you use to be
You're sick, my black giant, you're very sick

You suffer from this deadly cankerworm
Which has eaten deep into your bone marrow
And spread all over your blood stream
So much so, your leukocytes could no longer fight
To protect and secure the body Structure
And your whole system has broken down

The symptom is like Kwashiorkor
Large head, lean body
(The head eating up the body)
And more frequent stomach diarrhea.
The disease is called B&C
Bribery and Corruption
