There's bierra, sierra, zierra but no ierra which is the underlying word for all of these mysterious things. I'm guessing it means someone that has a tattoo on their ass and a smile on their face. All while crying. It sounds like the beginning of a new ierra (get it era?)
It's the beginning of a new person, their first intail doesn't matter but its a new IERRA.
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".
