A variation of the word cunt. Can be used when you want to sound more sophisticated when using what is arguably the most offensive term know to the language.
It makes use of sounding a bit latin, when in reality it can be deciphered as calling someone a massive cunt, big cunt, or of someone being such a cunt, that they could not be more of a cunt if they tried.
Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".
