Naughty head. The lowest of the low. This special combination of words is reserved only for the scummiest of scum. Said scummy person has to have committed at least two capital crimes (Murder, Terrorism, Pedophilia etc.) and Pedophiles in general.
This word can also be used for the big greedy corporate wall street CEO's that only care about themselves.
Some real life examples of a few naughty heads:
Charles Manson (Serial Murder)
Osama Bin Laden (Terrorist)
Semion Mogilevich (Fraud)
John G. Stumpf
You get the idea. Please only use this word when you really need to.
